How about a card that takes the 15-20 power you've accumulated on board, jumps it all into the air, and doubles your damage output closer to 30-40 damage instead
It can generate a ton of value, since we should have no problem returning it to our hand again and again
The risk-reward of this card stops it from being near the top for now, as you could theoretically pay a high cost to boost the power of a creature just for them to be removed, but that's where your understanding of the game and being aware of your opponents' mana comes into play
You could end up with a card that ran through the washing machine, or you could end up with a card that has a tiny pen mark but is otherwise lightly played
Would you run these in your Cube or EDH deck
