Notes & Combos
Tenpai
Just another tenpai deck, had the cards already and wanted to farm more gems, it was super easy mode with it, no need to think on most duels.
Droplets is the best card of the deck, even if my aproach didn't rely on boardbreakers, would definitely up it to 3 copies if i had resources to do so. That card is so broken in tenpai because it can inutilize your oponent's entire setup on most cases and going second you could just discard all your hand but one engine card and still otk, it also helps when you are forced to go first or when you can't otk as an interaction.
You also shouldn't search with sangen sumoning if possible, it is a 1/1 trade but it could take an ogre in response, in which case you lose the search and the field spell. Sangen sumoning is importante because it protects your entire field from ANY interaction, full protection from anything but floodgates and lingering effects, if you can get to dragion on mp1 it also means your oponent dosn't have any openings.
I was close to removing shifter from the deck, it is a insta win against most of the decks on the game but i had bad luck with it and it was never on the opening hand. Shifter also does hurt tenpai, it is just played because you can still otk and it does hurt other meta decks more than tenpai, but shifter means you can't use droplets, veiler or maxx C afterwards, fadra bnecomes useless and your resources get lost for good, you will sumon a lot less under shifter and deal less damage.
TURN 1:
Literaly your only play is to seals or s:p pass. If you are lucky your oponent will missplay and use a maxx C or shifter and you could negate it with gamma to make stardust and baronne in adition to seals or s:p.
Gring game
Tenpai's grind game is strong when the gamestate is simplified, if you don't have the field spell to protect your plays one handtrap will stop tenpai but if you also don't let your oponent play and get his cards on rotation, it gets really hard to out a fadra with just main deck cards. Any draw on the deck can be a handtrap to stall for one more turn or the one card you need for a full otk combo.
