lugia duraladon deck heavily tested with a 92% win ratio in ptcg live out of 500 matches reliably beats lugia, mew, regis, Zoro box, blissey, and zoroark vstar.
Weakness, bench sniping against archeops and lost vacumm on big parasol to use ohko or status effect moves also semi weak to item lock you can still use supporters to discard archeops but less reliable
when played to strengths you can have a no weakness 330 hp vmax that takes 30 less from v pokemon cant be damaged by special energy pokemon has a 300 damage shred attack and cant be affected if you have 4 of the single strike energies a vgaurd and a big parasol plus the 2 required aurora or impact or coating energy
bonus the energy engine aka lugia arceops by itself can win matches without duraladon
also if wanted you can substitue a card for any radiant of your choice but if you do so the best radiants would be charizard, jirachi, or grenninja.
when crown zeneth comes out you should 100% include radiant eternatus
