Monsters have been a huge part of Magic: The Gathering since the beginning. During that time, the game used a lot of pre-existing fantasy monster archetypes to create a wide menagerie of beasts for players to use against each other, from dragons to demons to minotaurs and more.
As the years progressed, they would expand, creating all-new monster types. Some of these creatures, like the Eldrazi would have massive power and toughness and be among the most powerful creatures ever created for the game. However, on the flip side, there are a lot of really weak monsters in the game as well. What are the five strongest monsters? Which are the weakest?
10 Strongest: Emrakul, The Aeons Torn
One of the Eldrazi, Emrakul, the Aeons Torn is a 15/15 for fifteen colorless mana. That's extremely impressive but that's not all: it can't be countered, players get to take another turn after casting it, it's a flier, has protection from colored spells, and annihilator 6.
On top of all of that, when it dies, the player shuffles their graveyard into their deck. Emrakul is kind of game-breaking when it comes down to it. It brings a lot of abilities to the table and the ability to swing for fifteen damage every turn is a huge advantage for the caster.
9 Weakest: Mindless Null
A zombie, Mindless Null is a 2/2 for one black and two colorless mana, which isn't terrible. In fact, it seems like a pretty useful creature to draw in the early game until players read its ability. It can't block unless the player controls a vampire.
A 2/2 for a low casting cost is only useful in the early game and it's rare that a player is going to have a vampire that close to the beginning of an M:TG game. Later on, a 2/2 isn't incredibly useful. It's just an all-around weak creature.
8 Strongest: Impervious Greatwurm
A Green Wurm, this 16/16 costs three green mana and seven colorless mana. That's a pretty good casting cost for such a large creature. It also has convoke, meaning the caster can tap creatures to take one colorless mana off of its casing cost. Green decks are usually built around creatures, so it's possible to put Impervious Greatworm out for three green mana.
On top of that, it has indestructible, which is where it gets part of its name. This is another kind of creature that completely breaks a game of M:TG.
7 Weakest: Zephyr Spirit
A Blue Spirit, this 0/6 costs one blue and five colorless mana, which is an extremely high casting cost for a creature with zero power, but its toughness is fairly high. However, it would be a mistake to think it was good at blocking because its ability is terrible: every time it blocks, it returns to the owner's hand.
Zephyr Spirit is a fairly useless M:TG creature. It can be used to block but there's really no reason to ever cast it again unless the player has surplus mana. It isn't even worth throwing enchantments on it to make it stronger because they'll just go to the graveyard when it hits the caster's hand.
6 Strongest: Colossus Of Akros
An Artifact creature, the Colossus Of Akros is a 10/10 for eight colorless mana with defender and indestructible, making it an amazing blocker. On top of that, it also has monstrosity. The caster pays ten colorless mana and Colossus Of Akros gains +10/+10.
Once Monstrosity is activated, it can attack as if it doesn't have defender and gains trample, making it into a 20/20 that can run roughshod over an opponent's creatures and hit the opposing player with that extra damage. It's a game-changer in any M:TG game.
5 Weakest: Takeno's Cavalry
Takeno's Cavalry is the definition of a useless White Weenie. First off, it's a 1/1 for one white and three colorless mana, making it a bit expensive. It has Bushido 1, meaning it gets a +1/+1 counter when it blocks and it taps to deal one damage to a Spirit, but none of that makes it worth its relatively high casting cost.
White is known for having a multitude of some of the most useful small creatures in M:TG, but this isn't one of them. Bushido is an okay ability and while Spirits were a big deal in the Kamigawa block it came from, it's just a very limited Tim wannabe.
4 Strongest: Marit Lage
Marit Lage is a 20/20 Legendary Creature with flying and indestructible and it's a token creature. That's right, a token. It can be brought into play using one of two cards: Dark Depths or Marit Lage's Slumber. With Dark Depths, a player must remove ten snow counters from it to put Marit Lage into play, and with Marit Lage's Slumber, a player has to control ten or more snow permanents to put it into play.
Either way, once it comes out, Marit Lage is a huge problem to deal with for the opponent, especially when paired with a Blue control deck. It's easily one of the strongest creatures in M:TG.
3 Weakest: Elvish Pathcutter
A Green Elf, the Elvish Pathcutter is a 1/2 for one green and three colorless mana. For one green and two colorless, it can give the target Elf forestwalk, which is useful if you're facing another green deck or can either change a land to a forest or swap control of lands, giving your opponent a forest.
Green is another color in M:TG known for having good weak creatures, but this isn't one of them. Its casting cost is too much for its power and toughness and its special ability doesn't do anything to make it worth a four mana casting cost.
2 Strongest: B.F.M. (Big Furry Monster)
The B.F.M. comes from the M:TG parody set Unglued. It's a 99/99 for fifteen black mana. A player has to have both B.F.M. cards to cast it and it can only be blocked by three creatures. It's easily the strongest creature in M:TG.
While it is part of a parody set and meant to be a joke, it's still the most powerful creature ever created, able to take out a player in one swing. It's not going to be seen in any tournaments, but it's still the strongest creature ever created.
1 Weakest: Aven Trooper
A White Bird Soldier, Aven Trooper costs one white and 3 colorless and is a 1/1 flier. So, right off the bat, it's a little expensive but not too bad. However, it can be pumped +1/+2... if you discard a card. There's not a lot of times in a M:TG game where discarding a card is going to be a good thing.
There are lots of 1/1s in the game, but even a 1/1 with no ability is better than one with a bad ability and that's Aven Trooper in a nutshell. It's too expensive and it's not even worth using its ability to pump it up to keep it alive.
