Enchant creature
Enchanted creature gets +2/+1, has haste, 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.
If, during its controller’s declare attackers step, the enchanted creature is tapped or is affected by a spell or ability that says it can’t attack, then that creature doesn’t attack. If there’s a cost associated with having that creature attack, its controller isn’t forced to pay that cost. If they don’t, the creature doesn’t have to attack.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
