You guys wont believe your eyes if you watch this video. This Chinese player reached KoG in the 1st day of the season (yesterday) with F2P Triamids!! Really impressive, hope you enjoy the replays.
The deck can stop traps and monster effects and just keep replacing field spells and getting more monsters out of their deck. Maybe it doesn't always start out so fast. But its also not exactly some amazing feat for this annoying thing to get KOG. Negating everything and destroying things at the same time seems to be the new norm for the new meta decks now.
It's pretty easy to describe what this deck does, everyone can do such thing. Reaching king of games in day one with a deck that doesn't have any UR in it is quite a merit. This deck doesn't rely in cheap tactics like burning your HP or special summoning 3 monsters asap, it's very healthy for the game. The devs are rewarding skills and brainy plays.
Who cares whether is has any UR in it? f2p isn't some new thing like you seem to think everyone else believes. It's not some big achievement to get kog with this deck when it holds your hand through everything with preventing a ton of effects and replacing the field spell all the time.
Sphinx will rape the meta so fast and hard it'll trigger a geological event, im getting three of every triamid card to be on the safe side, because when Sphinx comes out... My God... I can hear the pay to wins crying in fear. It will definitely go tier 1
