Spells your opponents cast that target Charix cost {2} more to cast. {3}: Charix gets +X/-X until end of turn, where X is the number of Islands you control.

Landfall — Whenever a land you control enters, target player mills three cards.

Ward {3} (Whenever this creature becomes the target of a spell or ability an opponent controls, counter it unless that player pays {3}.) Channel — {2}{U}, Discard this card: Counter target spell or ability unless its controller pays {3}.

Landfall — Whenever a land you control enters, each opponent mills three cards. (To mill a card, a player puts the top card of their library into their graveyard.)

{6}{U}: Monstrosity 4. (If this creature isn't monstrous, put four +1/+1 counters on it and it becomes monstrous.) As long as this creature is monstrous, it has hexproof. (It can't be the target of spells or abilities your opponents control.)

Enchant creature {2}{U}: Untap enchanted creature. Umbra armor (If enchanted creature would be destroyed, instead remove all damage from it and destroy this Aura.)

You may return two Islands you control to their owner's hand rather than pay this spell's mana cost. Draw two cards.
