Control the other player by cock blocking every move with exile creatures or enchantments, can't attack or block, destroy attacking creature, destroy creatures with 4 or greater power, and block with creatures that die returns as a 1/1 flying spirit token or as +1/+1 counter to other creatures or +2/+2 counter to human creatures.

attack with spectral rider [2/2 two to cast with Intimidate] and angel of flight alabaster [4/4 five to cast with a return spirit creature to your hand at the beginning of your upkeep] while casting moment of heroism [target creature gets +2/+2 and gains lifelink].

and the best part here is that it costs far less than the deck you're blocking.
