Yeah, thought some time yesterday about Mono-Gravity and Mono-Gravity with splash, and I think 40-ish cards is the best (high cost cards FTW). I think this can help Massive Dragon see some use, and I will se what I can do with the unupped one
I will follow this idea while I develop my own unupped mono-gravity/mono-gravity splash with dragons.
BTW, you should check the Quanta Index of the deck, and keep it as low as possible (3-4), big critters -Massive Dragons- need low QI.
