Flying If you control five or more untapped lands, this creature enters with two +1/+1 counters and a lifelink counter on it. Plot {1}{W} (You may pay {1}{W} and exile this card from your hand. Cast it as a sorcery on a later turn without paying its mana cost. Plot only as a sorcery.)

First strike When Impetuous Lootmonger enters, discard a card, then heist target opponent's library. Whenever you cast a spell you don't own, create a tapped Treasure token.

Flash Flying When this creature enters, exile target spell. It becomes plotted. (Its owner may cast it as a sorcery on a later turn without paying its mana cost.) Spells your opponents cast from graveyards or from exile cost {2} more to cast.

First strike, Lifelink When Stalwart Realmwarden enters, the next noncreature spell target opponent casts costs {2} more to cast.

Flying As long as this creature is untapped, creatures can't attack you or planeswalkers you control unless their controller pays {1} for each of those creatures. As long as this creature is attacking, creatures can't block unless their controller pays {1} for each of those creatures.

Indestructible, haste At the beginning of combat on your turn, put a +1/+1 counter on Tajic, Legion's Valor. Then conjure a card with mana value equal to the number of +1/+1 counters on it from Tajic, Legion's Valor's spellbook onto the battlefield. It gains haste until end of turn and attacks this combat if able.
