Enchant creature
(Target a(n) creature as you cast this. This card enters the battlefield attached to that creature.)
Enchanted creature gets +2/+1, has
haste (This creature can attack, and as soon as it comes under your control.), and attacks each combat if able.
When enchanted creature dies, you may search your library for a card named Infectious Bloodlust, reveal it, put it into your hand, then shuffle.
