This build has a focus on solely using one of the two variations of the one card combo, or, if you have 2 prank-kids in your hand, 2 card combos that only summon 4 times in a turn. With the room saved from not needing polymerization, ultra polymerization, or cards that search them, it is able to play a plethora of hand traps, making it much stronger at going 2nd compared to other builds, while not sacraficing much strength in going first.
This build is focussed more on TCG rules, even though it has crossout designator. Parallel exceed cannot chain block using OCG rules like it can here in the TCG:/
Either way, this is a super rewarding deck to become familiar with!
