Getting Mobius vibes from this one for whatever reason.
VJMP-JP190 Jinrai no Boukun Grozer / Grozer the Thunderclap Tyrant
Lv 8 DARK Synchro Monster
Today’s blurb is “A Synchro Monster that will play a big role in Fiend Decks!!”, with an additional caption that elaborates with “A Level 8 Fiend-Type Synchro Monster with an effect that synergizes well with the “Fableds” powered up in Blazing Vortex.”
Note: The monster’s name seems to be based on “Гроза” (Groza), the Russian word for “Thunderstorm”.
