Notes & Combos
I totally give up on one-time-negate-one-effect going second cards like ash, imperm, and veiler, donnot tell me ash can stop MAXX "C" and Fuwalos going first, our opponents are playing something containing Kash+SE/Yubel+Azamina+Fiendsmith, when you play with such a thing, those handtraps are just trush. But no offense, I'm only talking about RR, RR is special in some ways, it can challenge the MAXX "C" of even Tenpai but still win. And RR's recovery strategy is garbage, and that means you either totally stop your opponent or you lose.
Remember to play 3 droll, it is GOAT in current META.
If you are an RR player and have questions about the list, just check the replays, you will know what I'm talking about.

As a fellow RR enjoyer huge respect for you my man 🐧🤜🤛🐧👍 This format is indeed **** rn but it is wat it is

If you have to replace it, then call-by the grave is the choice. But call-by is a card better than reboot going first but much weaker going second, which is not preferred since RR has many ways to play around normal handtraps like ash, veiler and imperm going first. By the way, reboot stops imperm completely, and when dominus impulse comes, that card severely threats RR even though RR can benefit from it itself, at that time one reboot helps you negate dominus impulse and dominus purge altogether going first, as well as imperm :).

yeah i just didnt want to craft it. What do you think about roost and glorious bright since you said rr recovery isnt good

Well, for roost and glorious bright, you can play them, but I won't recommend to do so, since these cards have no use in going second or going first under MAXX "C". If you go first under MAXX "C", the best way for RR is to challenge it, and Kali Yuga the opponent to win, anyother plan B strategy won't help too much, because the starters of RR are much weaker than todays' cards like Diabellstar and Engraver, so a long match will almost always result in losing the game.

Of course, in turn 1 it can be summoned by RUM Force, in turn 2 it can be summoned by RUM Force and RUM launch on Typhoon. The turn 2 case comes more since in turn 1 you typically summon another Ultimate Falcon with 2 material to have twice lock in turn 3, unless you know your opponent directly loses to RRF such as branded.

Not recommended, actually I did play Evilswarm for a while, to summon it after eating MAXX "C", but the result was bad, Evilswarm could not stop current meta decks, and it takes 2 level 4, that means it will take about 2 or more turns for RR to organize another board making. If not for MAXX "C" purpose, I might never play it, since the endboard of RR is already powerful enough, the tricky part relies in how to counter super poly and kajus.
