Rate my spellcaster deck please?

Looks really good, but for spellcaster you don't need that insta-destroy, so I would take out sakuretsu armor, and also your deck flows so you don't need the show-stopper that is metal reflect slime, that is for players who need a wall to draw out their decks, I would replace those with x2 savage colloseum.....and hey since you are a vet. and all at this, can you swing by mine and let me know what I can do differently/better?
