Aye, that sounds best. Notes:
Entropy MA will need as many Lightnings as can be spared. 4-5 Dims.
Earth MA will be rushier, probably still needs some Lightnings. Haven't looked thoroughly at what they have left yet.
BoneBolt for Time needs the Poisons upped and 2 Mummy/2 Fractal, probably 12 pends. Fill up with Arsenics after BW's and Lightnings. Needs to withstand Discord duo, Dim Shield duo and Sanctuary duo. Poisondial will be big trouble. Fractix might be able to deal with all.
NovaGrabby for Death will probably go full on rush, using all the support cards we have for it (Fog, Momentum, etc.). Focus on PU's and more Pends (no more than 5 needed, then Pillars) rather than Lightnings.
Gotta host tourney now, so please cook these up.
The decks we can consider switching are Earth MA and Death NovaGrabby.
