Sorry my english is bad, is very consistent 90% win in one duel against Lv 400 or 300 is important summon any of 3 synchros un the first turn and equip with any the equip spell or tyrant so you attack 3 time for turn and you can change trident for Dynatherion
Ah, I see.
But now I'm trying a different combination, no signer Dragons, but I've gotten synchro monsters who can inflict piercing and they are lv6, no equip as I tried changing for more drawing cards.
But I've going to test your deck too. So, thanks for your help
