I've always been a fan of deceptively simple designs and I wanted to see if I could make a blue control finisher that hits most of the boxes without filling its text box. What I ended up with was...
Fountainhead Leviathan
Creature- Leviathan
Flash
Fountainhead Leviathan can't be countered.
Return Fountainhead Leviathan to its owner's hand: Draw 2 cards.
6/6
While I doubt that anything like this will ever be printed, a man can always dream.
I'm mean as far as completely broken cards go it's fairly tame. I mean it's obviously broken but only in the specific state of a control deck. It being completely immune to removal and is card advantage when ever you want it's insane. Honestly a seemingly broken ability like protection from everything would be far more reasonable that the last ability.

How about this execution:
Blinking Drake
2UU
Creature - Drake
Flash. Flying.
Return Blinking Drake to owners hand: draw a card.
2/1
Would this be printable?
An indestructible Treasure Trove that deals 2 damage a turn is pretty great but isn’t insurmountable.
probably on a similar power level to Reflector Mage. The fact that plague engineer shuts this off is notable, I think.
Probably not the sort of card you’d get in a standard-legal set but I can imagine it popping up elsewhere.
