Only change I made was replaced 1 Shard of Greed with Golden Ladybug. Once you have an Unhappy on the field with Spirit Barrier, you can use Rai-Mei to search Golden Ladybug and start stacking LP for Ra summon last turn.
Could forbidden chalice replace divine wrath? If Im not mistaken divine wrath role is to counter daedalus. But daedalus need a field spell to active its effect and Zane only have 1 field spell.
If Ra ha 5000 ATK... ?? ^^
You just have to use the spell supremacy berry before summoning Ra.. Ra's ATK are as high as you pay LPs while summoning him...
Then 2x union and secret pass... and here you have your 10k damage
No, because if you summon Ra with full LP he will get 3900 / 3900. You automatically pay all LPs you have to 100 LP. So if you have 5000 LP Ra will get 4900 ATK and 4900 DEF
