Syrix, Carrier of the Flame

Destroy all nonland creatures. Awaken 4—5WWW (If you cast this spell for 5WWW, also put four +1/+1 counters on target land you control and it becomes a 0/0 Elemental creature with haste. It's still a land.)

Choose three. You may choose the same mode more than once. • Create a token that's a copy of target creature you control. It gains haste. Sacrifice it at the beginning of the next end step. • Exile target artifact or enchantment. • Creatures target player controls get +1/+1 and gain first strike until end of turn.

2, T: Exile the top card of your library. Until end of turn, you may play that card. Put a brick counter on this artifact. T: Exile the top card of your library. Until end of turn, you may play that card without paying its mana cost. Activate only if there are three or more brick counters on this artifact.

Choose three. You may choose the same mode more than once. • Return target monocolored instant or sorcery card from your graveyard to your hand. • Target creature gets -3/-3 until end of turn. • Goad each creature target player controls. (Until your next turn, those creatures attack each combat if able and attack a player other than you if able.)

Choose two — • Target player loses X life. • Return target creature card with mana value X or less from your graveyard to the battlefield. • Target creature gets -X/-X until end of turn. • Up to X target creatures gain fear until end of turn. (They can't be blocked except by artifact creatures and/or black creatures.)

Each creature spell you cast with mana value 4 or greater has blitz. The blitz cost is equal to its mana cost. (You may choose to cast that spell for its blitz cost. If you do, it gains haste and "When this creature dies, draw a card." Sacrifice it at the beginning of the next end step.) Blitz costs you pay cost 1 less for each time you've cast your commander from the command zone this game.

Whenever a creature attacks one of your opponents or a planeswalker an opponent controls, that creature gets +2/+0 until end of turn.

When this creature enters, put a shield counter on target noncommander creature you don't control. You gain control of that creature for as long as it has a shield counter on it. (If it would be dealt damage or destroyed, remove a shield counter from it instead.)
