If you want to do some really silly things, you could always try effects like Warp World
When its summoned using an XYZ monster as a material (its kind of complicated, but this is possible through a weird combo) you can destroy all level 7 or lower monsters that your opponent controls, inflict 1000 damage for each one, and then this card can attack 3 times in one turn
Theres a decent amount of card removal to help enact your game plan, too, while Yuna, Grand Summoner and Walking Ballista still command a decent price
Then, rip the card you believe is fake
Master the elements alongside the Charmers and their familiars with Structure Deck: Spirit Charmers
3: Once per turn, when a card or effect is activated (Quick Effect): You can negate the activation, and if you do, banish that card
