Yeah, but it is nice to drop stone formed gargoyle, 6/6, and phoenix (or various combination) and have the ai fruitlessly waste rain of fires.
RoF's? are you using this versus T50? If so how well does it work.
Yeah I built this to grind t50 with (because I was trying to get pulvies for ccyb)
The deck I was using was only mostly upgraded (the important ones, pretty much. had unupgraded like... two frogs, which i later switched for heals to up my EM rate, 2 graboids since upgrading only gives +2 atk, etc). The winrate versus mono life was pretty much under 10%, unless they got really lucky. Mono life just trounces all over this deck, and if it's the mono life EM version (with heals) it's impossible to win unless they don't draw any heals.
It tends to win against every rainbow except for the rainbows that include otyugh and rain of fire (they usually include things like many sundials and phase shields that only stall until they can RoF/Otyugh and shut you down).
It stomps vampire rush (unless they get a good starter), and all poison rushes that I've faced.
RoL/Hope (the speed version. dragons, RoL, Hope, and Lobo) comes down to whether or not you get unstable gas; if you do, you win automatically, if you don't you lose 50/50. Unless it's a different variant of RoL/Hope (with shards and stuff), and then you just win because they don't third turn hope you like the speed variant does.
All in all the only auto-quits this deck has is mono life. Everything else is pretty winnable (the rainbows got hairy for me depending on draws, but I usually lost by enough that it wasn't solely because it wasn't totally upgraded).
