Enchant creature you control
Enchanted creature gets +1/+1.
When enchanted creature dies, you may search your library for a creature card with mana value equal to enchanted creature's mana cost minus 1, put it onto the battlefield, and attach Chain of Command to it, then shuffle.

Chain of Decimation deals 4 damage to target creature, 3 damage to two other target creatures, 2 damage to three other target creatures and 1 damage to four other target creatures. (You can't cast Chain of Decimation unless it has ten targets.)

Chained Greatwolf enters with a defender counter on it.

Whenever a creature an opponent controls becomes tapped, put a +1/+1 counter on Chalkira Duelist.

Permanents you control with the chosen name have hexproof and the “legend rule” doesn't apply to them.

Double each number and amount of target instant or sorcery spell, activated ability, or triggered ability. Its controller may choose new targets for it. (Amounts are number words, X values, and “a” or “an” used as 1.)

Whenever you cast a noncreature spell, if you control exactly one creature, copy that spell. You may choose new targets for the copies. (If it's a permanent, it resolves as a token.)

Search your library for three differently named noncreature, nonland cards with mana value 3 or less not named Chaos Is Your Redemption and exile them, then shuffle. If you exile three cards this way, cast one at random without paying its mana cost. Then shuffle the rest into your library.
