Rokket Resonator

[Thomas★Zero 19]

Rokket Resonator
lv 2 DARK
Dragon/Tuner/Effect
When this card is Normal Summoned: you can Special Summon 1 Level 4 or lower DARK Dragon monster from your GY. During the turn you activated this effect, you cannot summon monsters from your Extra Deck except DARK Dragon monsters. If you use this card you control for a Synchro Summon, you can treat it as a Fiend monster. During your Main Phase: you can banish this card from your GY; add 1 "Rokket" or "Resonator" monster from your deck to your hand. You can only activate this effect of "Rokket Resonator" once per turn.
ATK/800 DEF/500

So Rokket Resonator acts as act a mix of Rokket Synchron and a Resonator Tuner where this card first can add a DARK Dragon from your grave to the feild, then, it can banish itself to search a Rokket or a Resonator. In addition to this it can also treat itself as a Fiend monster where it then acts like a proper resonator monster.

In Rokket decks this card can engage the Red Dragon Archfiend Levels of Synchro Summoning where if you have a Level 4 Dark Dragon in the grave you can summon this, get that monster from the grave on the field and then summon Red Rising Dragon to bring this back in order to go into either Borreload Savage Dragon or Scarlight Red Dragon Archfiend.

Looks both greedy and cookie-cutter/no-brainer to me with the revival + search, but Resonators and Rokkets aren't really doing much so I guess it is fine? IDK, they could start doing things with this card, though. Adding a Dragon-Ruler-like hard OPT may be a more fair thing to do. I find amusing that the Summon lock doesn't affect Guardragons too much, since the Links are DARK.
