Mana Vault [Fourth Edition] Incarnation Urborg became the final resting

Urborg became the final resting place of many swordsmen of renown

and the second player controls the first player during the first player's next turn

Then if you have more life than an opponent

reveal the top card of your library and put that card into your hand

you'd need the energy of the giant's tonic
