As of right now, there are two cards for doubling tokens in MTG
Aeve, Progenitor Ooze is a five mana Green 2/2 that isnt legendary as long as its a token, and it enters with a +1/+1 counter on it for every other Ooze you control
Both colours give you Evasive characters like Pongo Ol Rascal and Peter Pan Never Landing which can only be Challenged by other Evasive characters which many Starter Decks lack
It always seemed a bit strange to me, but its an accepted fact in that community
While the archetype has a host of mono-black options, the death trigger makes this a nasty threat: Pinging your opponents as zombies die gives you another angle of attack and means Wrath of God might not be enough to salvage a game
This is because every single time this card quests, you can give another character the keyword until your next turn
