Red Dragon Archfiend

You can use Crimson Resonator with a level 4 monster to summon Red Rising Dragon, then use Rising dragons effect to summon crimson back, use crimsons effect (only if you only control crimson and red rising) to summon 2 resonator monsters from your hand or deck (2 red resonator or creation resonator and synkron resonator) (if you use red resonator you can use one of them to gain LP equal to the attack of one monster on the field) and use all 3 tuners and red rising dragon to summon red supernova dragon.

There are multiple cards to use as defense against opponents cards and to get the cards you need to summon your synchro monsters
