Well, there's the hilarious way to win with Fling
If an attacking Human is tapped for Minas Tirith Garrison's ability (perhaps because it has vigilance or it was untapped after being declared as an attacker), that Human remains an attacking creature
If she banishes a character she also deals two damage to another opposing character - that even includes characters who arent exerted
If you trigger that Blood Artist effect four times in one turn, you transform Sephiroth to his reverse side, Sephiroth, One Winged Angel
Turntimber Symbiosis comes into play untapped when needed, further lowering its opportunity cost, and since green decks tend to have big finishers like Craterhoof Behemoth, being able to dig seven cards deep in your deck to find them is quite powerful
But keep in mind, it's only current characters that lose their strength.
