Creature - Sphinx Fallen Shinobi Ninjutsu (, Return an unblocked attacker you control to hand: Put this card onto the battlefield from your hand tapped and attacking.) Whenever this creature deals combat damage to a player, that player exiles the top two cards of their library
Most decklists run three copies, while the Pure Pult lists only even run two
Anything you put into your deck, other than situational spells like Counterspell, is going to be something you want again
Pair this enchantment with discard cards like Dark Deal and Rankle, Master of Pranks, and you should be rolling with the benefits
The card gives you board presence, ramp and mana fixing, card selection, and finally, a solid imitation of one of the most notorious creatures of all time, Kiki-Jiki
