When you play a card from anywhere other than your hand, empower me.
[Action][>] Disempower me, : Give a unit [Assault 2] this turn. (+2 while it's an attacker.)

When you play me, [Burn 2]. (Put the top 2 cards of your Main Deck into your trash.)
When I conquer, give a spell in your trash [Flow] equal to its cost this turn. (You may play it from your trash for its Flow cost. Then banish it.)

[Hidden] (Hide now for to react with later for 0.)
When you play me or I attack, you may pay 2 to [Stun] a unit. (It doesn't deal combat damage this turn.)
While there's a stunned enemy unit here, I have +2 .

Look at the top 3 cards of your Main Deck. You may choose a card from among them and draw it. Put the rest into your trash.
[Flow] 2 (You may play this from your trash for its Flow cost. Then banish it.)
