Trap card monster decks are prone to being destroyed by backrow removal cards such as Sacred Phoenix of Nepthys, Darkstorm Dragon, Storm, Straight Flush. These cards are capable of removing all your backrow Spell/Trap that includes Tiki Soul, which means Tiki Soul will not be able to protect your Trap monsters.
Other cards such as Xing Zhen Hu, Sergeant Electro, Chow Len the Prophet that has the effects of locking down your backrow Spell/Trap zone can also be a potential threat. This can be quite dangerous if your backrow is clogged up, it will be very hard to use other Spell/Traps to turn the tide and you have to rely solely on your monsters.
Continous Trap Monsters
These are the monsters that is able to utilize Tiki’s Curse’s effect to destroy your opponent’s monsters faster. Tiki Soul has the most synergy with Tiki’s Curse as it is able to set Tiki’s Curse back to your backrow should your opponent destroy it via battle or card effect. Having multiple Tiki Soul could potentially grant indestructibility for all your Trap Card monsters.
Endless Trap Inferno Can be used when you have 3 trap cards in the Graveyard. 1 random Trap Card in your Graveyard is added to your hand. Then, shuffle 1 random Trap Card in your Graveyard into your Deck. This skill can only be used once per Duel.
Wording that kind of effect was awkward. I agree, the wording seems to imply it needs to CURRENTLY be both a Trap and a Monster, but the intent is clearly a Trap Card that became a monster, regardless of if it's still a Trap. Kinda wish they had gone with a monster that was originally a Trap. Though the only card that could do that at the time was Magical Hats.
