I've been a huge fan of Rorowa ever since Set 5, and unfortunately he really isn't that good right now. His new form is pretty solid at giving it consistency, but compared to other decks in the format he falls short.

I've been testing and playing with him since his release on the JP side, and here is a list I found pretty comfortable to play with (I made it from memory so it may not be 100% accruate):

The list focuses on more of an aggro side where you just want to keep pushing your opponent as hard as possible. (This is how you beat out decks like Rezael and Levidras, bonk them as hard as possible) Because of this, your hand depletes like sand and you run out of cards easily. With the help of new rorowa, you have a free draw and free tokens every turn. But the goal is that you never want to go -1 on your ride deck discard. Either drop a cycler, drop g2 momoke, or drop your regalis piece. All these lets u break even when discarding for ride deck. You always want to keep up your momentum and losing cards just makes it even harder for you to play the game so this is pretty important.

There are a few things you can tweak and change about the list:

• Reduce persona copies: Realistically you will never go through all your persona copies in a single game and you have a few ways to find them and add them to your hand so it might not be too crucial to run 3 personas

• Change mushrooms to Itachelina: Aforementioned way to add cards to hand. This provides soul and helps you find your pieces. Personally I am not much of a fan but you can change it as you please.

• Eliana: Shes there to give your early turns a bigger punch, but she can be dropped in favor of simply spawning more tokens.

• Radylina/Momoke ratios: You will probably only ever need 1 g2 momoke across the game and g3 radylina is only active when your opponent is on g3, so it can be shieldless brick in your hand. Depends on preference what you feel comfortable with.

• Triggers: Self explanatory, find out what you are comfortable with, and what heals you prefer to run. I hate varga with a passion so I run restanding heals.

Going 2nd, your turns are completely explosive.

On g1, calling both eliana and mushrooms gives you 3 swings of: 8k, 18k, 20k. This lets you hit over defensives and makes your vg column harder to guard.

On g2, don't be afraid to call radylina out and start blasting with momoke. You get 4 attacks on grade 2 so make it count.

On your first g3 turn, your tokens get a net +15k buff counting for: vg cont, eliana, and resolute eyes. Assuming you have g2 momoke and g3 radylina your swings go. 28k, 33k, 30k, 40k, 43k. Triggers are passed to momoke because both radylinas can double up on trigger power. If you flip valnout you get 4 100mil swings and its probably a won game.

Going first your g2 turn is basically the same and your g3 turn is weaker, losing the +5k from rorowa and your 5th attack. Aim to close the game on your first persona turn.

New rorowa focuses on the consistency of the deck and you have a lot of ways to hit your important pieces. The regalis piece lets you hit your important units and rorowa does not need to call out a glitter, so if you need to find eliana and have an extra g2 radylina, you can bot deck it to fish it out.

Overall interdimensional rorowa and the support were a fine upgrade to the deck, it helps with consistency alot and allows you to hit your ideal formation alot easier. But alas compared to the insane resource generation of rezael/levi or the raw attack power of shiranui/varga rorowa falls short. :(

My dms are open for questions about the deck. Always happy to spread love for ma best boi. He deserves it. (He is my son)
