Tbh I think the effect is underwhelming. Tachyons effect is an ATK gain too but also negation and multiple attacks. This card raises attack while already having 4000 ATK so kinda meaningless it can only negate once upon its summoning and can only attack once. It's harder to summon and does almost less then The lightning.

Cool card on it's own but the effect needs a bit refining for a tachyon card
