pokemon tera charizard card TCG EX you may search your deck for up to 3 Basic [R] Energy cards and attach them to your Pokemon in any way you like Charizard ex 125197 Double Rare

The negative of both abilities is that it can only eat Swamps and Islands, making some of the other dual lands less than ideal

The cost of discarding a card can also be a great way to get a big creature out of your hand for a cheaper reanimation spell, allow you to set up evasion with a creature like Filth, or just turn that land you dont need on turn 10 into whatever the biggest threat in your graveyard is instead

Note: I will be primarily discussing these card's implications in non-rotating formats, so please keep that in mind

Force of Will (8.5) is obviously the premium in hardness and cost but you have to have sufficient disposable blue cards in your deck to have it be any good and that is a little harder to do than it sounds with so many combo pieces in your list
