Still tinkering with Spright Evil Twin. This build is back to the Sprights being a supplementary engine - while Spright full combo does still exist, you're trying to make Trouble Sunny reasonably often. The deck has multiple lines depending on how you want to play and what you want to end on, and whether you're going first or second. It think it is great you can maindeck 2 Ultimate Slayer for pure profit as well. This is a combo/control deck that has tools to grind in the long game, but is capable of putting up "huge" boards in the short game, though you may be lacking in ATK points.
I opted for board breakers instead of imperm - our goal is to push through a field of negation and set up interruptions on the opponent's interruptions in the process. This list is as likely to summon Red to protect a Trouble push as it is to put up the Double Toad. I opted for a small as possible Frog engine, and as few bricks outside of Twins as possible, so that the deck can really push through for game without bricking out on bad cards (I should also point out, in this deck Twins enables OTKs and can help break boards, unlike most Slayer builds,)
Side deck is cards to out Mystic Mine and generic backrow, cards to break boards even better, and the Artifact Sanctum package so we can Scythe lock people going first.
I feel like Chalice is really good right now, and Enemy Controller is a pushed card going second in Twins,
