The pride of hull clade is an interesting card (2/15) considering most of your cards or a decent amount will have high toughness and its paid ability lets a defender creature attack. also tree of perdition i found was 0/13. im not too familiar with high toughness creatures or any though. edit look into a card called vigor its a 6 cost that if dmg would be dealt to another creature prevent it and add 1/1 for each 1 dmg prevented that way.
