MTG Azorius Midrange Deck by Jeffrey Zhang

When this enchantment enters, exile all graveyards. If a card or token would be put into a graveyard from anywhere, exile it instead.

Choose target spell or permanent that's red or green. Its owner puts it on their choice of the top or bottom of their library.

This spell can't be countered. Counter target noncreature spell.

+1: Until your next turn, prevent all damage target permanent would deal. 0: Until end of turn, Gideon becomes a 4/4 Human Soldier creature with indestructible that's still a planeswalker. Prevent all damage that would be dealt to him this turn. 0: You get an emblem with "As long as you control a Gideon planeswalker, you can't lose the game and your opponents can't win the game."

This spell costs {2} less to cast if it targets a blue spell. Counter target spell unless its controller pays {3}.

When this enchantment enters, you may exile target nonland permanent not named Detention Sphere and all other permanents with the same name as that permanent. When this enchantment leaves the battlefield, return the exiled cards to the battlefield under their owner's control.

Exile all attacking creatures target player controls. That player may search their library for that many basic land cards, put those cards onto the battlefield tapped, then shuffle.
