Strategy is to summon Imperion Magnum the Superconductive Battlebot as fast as possible.
there are a lot of ways to search Berserkion and Valkyrion to you hand as well as summon Valkyrion from deck using deltas effect. there is also only two copies of prisma to substitute for one of the two.
Alpha can search both Berserkion and Valkyrion from deck to hand when summoned and doki doki can summon alpha from deck to get that search. Block dragon is decent and can also search them when destroyed but has a high cost which is why it is at one copy. Delta can summon Valkyrion from deck however he needs three magnet warriors in GY to banish that are not delta so there is one copy of Gamma the magnet warrior because Alpha, Beta , and Gamma the electromagnet warriors can all special summon 1 level magnet warrior from deck so it is just there for banishing from GY.
