Notes & Combos
Although we don't have Terraforming, Tenpai still feels broken right now because of Sangen Summoning at 2. Me like make big dragon go brrrrr....
If you don't know how to play the deck here are some tips:
If you are made to go first, just try to set up a Heavenly Spheres and a set Sangen Kaimen, and you should be able to beat the mirror match if you toggle on and immediately make Transcendent Dragion as first action in the battle phase. With the ammount of handtraps you have in this build, you almost always shut them off from being able to make Transcendent before you in the mirror match, nearly guaranteeing victory.
If they do something that seems out of the ordinary like normal chundra or normal Dora Dora as their first action, immediately seals it back to hand. Chances are they don't have any other plays.
For going second, your goal is to always have a Sangen Summoning up with a Transcendent Dragion and a Sangen Kaimen in hand. If you play this correctly and don't get rid of your Transcendent Dragion, it's beyond game.
Other than that, if you don't make any blatant misplays and you have an understanding of how your opponents decks work, then you'll be fine.
If I was to make any changes to the decklist, I would probably cut S:P as I only summon her to out things like bagooska. You could play Kuibelt and another synchro 7 or whatever you want instead of S:P and Striker Dragon and do just fine. Other than that, the decklist was great for me, I went on an 11 game win streak in diamond with the deck before I ranked up.
