It's easy to summon in a galaxy focused deck by using Galaxion, summoning a GEPD via its effect and then using the new trap to summon the beater. The only problem is that there is no way to equip it with GEPD to trigger it's effect
Only his first effect (negate) requires GEPD to be one of the material upon summon.
Second effect can be used regardless as long as NGEPD have Xyz material and opponent have Xyz monster with at least 1 material.
So yeah, it is still a beater without GEPD, but it is a beater that can potentially attack 2 times or more.
