Notes & Combos
This deck doesn't produce as crazy of an end board as other decks but what this deck has to offer is that it's extremely consistent at making a 5-8 interrupt end boards with just 2 generic cards. It also has some board breakers in-case you ever go 2nd. The idea of the engine is to swarm the board with Traptrix monsters, set up the Trap Holes, and then pivot into making a slightly weaker "Rikka" end board - which would also include a Sera that would be ressurected on your opponent's standby phase through Holeutea.
In the off chance you do cannot start a "Traptrix Combo", Mudan is a 1-card combo that could atleast make a board with 2-5 interruptions depending on the hand.
If you do not like the lack of the roach, you can change a copy of Primula and DRNM to a 2x Maxx C instead. However, personally, I think Maxx C is just a brick. Ash is vital because this is a combo deck, but Maxx C is not really that important because this deck is already consistent as is.
If you got Maxx C'd and you have no Ash, you can just revert to just have a Sera and then 1-3 set and pass lol.
Notable Bricks on the hand: Dionea Pudica
Cards that become bricks on certain situations: Petal Snowdrop DRNM Evenly Matched (rarely, since you can use it as Holeutea fodder often going first)
