Card sounds may differ from in-game as they get updated.
Charge - Can attack the turn they are played.
Endurance - Units with Endurance ready at the start of each players turn, so they can attack and still be ready to block during the enemy turn. Additionally, they are completely immune to enemy stun and exhaust effects.
Flying - Flying units can only be blocked by other flying units, but can block ground units normally. They can also be directly attacked by Killer units and Relic Weapons.
Contract - You may pay the number in additional power to get its bonus. If you don’t have enough power to pay some or all of the Contract, the remaining balance is applied as “debt” that is paid at the start of the next turn.
Debt - Your available power is spent to pay off Debt. If you can't pay it all, you pay at the start of your next turn.
