Count the Might before the swap resolves
Switcheroo · Teemo, Scout
Switcheroo compares the current Might of two units at the same battlefield as it resolves, then lowers the larger one and raises the smaller one by the difference for the turn. Teemo, Scout enters with +3 Might for the turn, so a 4-Might Scout swapped with a 7-Might attacker becomes 7 while the attacker becomes 4. Each battlefield normally holds one facedown card, so if Scout was the card hidden there, Switcheroo has to come from your hand for its full cost. The swap does not copy the enemy's abilities.
