I have summoned thunder dragob with thunder dragons hundred thunder effect and summoned fire ant ascator, but i cant synchro summon Sun Dragon Inti, i summoned it once but then until now i couldnt summon inti, anyone know how? Is it bug or do i missplay? :(
Thunder Dragons' Hundred Thunders trap effect prevents you from special summoning monsters, except Thunder monsters. Synchro Summoning is considered a special summon. Therefore, it is not a bug.
i CaN't ReAd CarDs.
But seriously thought, please know your cards before you play them and if something not working out, then there is something you missed/didn't read.
It's not a bug, it just a misplay on your side.
with the trap you mentioned you can only special summon thunder monsters as long as those are on the field
