When this card is Normal Summoned: You can Special Summon 1 Level 4 or lower monster from your hand. When this card is Special Summoned: You can target 1 face-up monster on the field; gain LP equal to its ATK. You can only use this effect of "Red Resonator" once per turn.
Can Special Summon a low-leveled monster from your hand.
Heals your LP.
Special Summoning a monster from the hand is not as effective as Special Summoning from other places.
LP gain depends on what is on the field.
Good for making generic level-6 and lower Synchro monsters.
Red Rising Dragon
One of the best monsters you can make with Red Resonator for extended Synchro plays. Normal Summon Red Resonator and Special Summon a level-4 monster, then make Red Rising Dragon. Red Rising Dragon can revive Red Resonator which activates its heal effect and sets up a level-8 Synchro Summon.
You can Normal Summon this card while you control Red Daemon's Dragon, Special Summon a second copy, use the Special Summon effect targeting RDD to gain 3000 LP, then Double Tune both Red Resonators with RDD to bring out Scar-Red Nova Dragon.
