This card is treated as a Normal Monster while face-up on the field or in the Graveyard. While this card is face-up on the field, you can Normal Summon it to have it become an Effect Monster with this effect.● Once per turn: You can send 1 face-up Spell/Trap Card you control to the Graveyard; destroy all Spell and Trap Cards on the field.
Effect can destroy all spell and trap cards on the field.
Tribute summoning him normally requires 2 tributes, and another normal summon to have the effects available.
Effect destroys your own spells/traps as well.
Revive with Blazewing Butterfly
Since darkstorm is a gemini monster, it can be easily summoned by using Blazewing Butterfly and have its effect up immediately.
Destroy all spell/traps
Herculean Power can be used in a gemini deck that are useful early in the duel. Once you manage to summon darkstorm, you can activate the ability by using herculean power to destroy all spell/traps.
Synergy with Supervise
Supervise allows darkstorm dragon to immediately gain his effect and can be used as cost to destroy all spell/trap cards on the field. In addition, when you send Supervise to the graveyard you can special summon a normal monster from your grave.
I play this on Red-Eyes. Quite useful. Spec. Summ. This via Return of Red-Eyes (because it's a normal monster in GY) then gemini summon then send return of Red-Eyes to clear all backrow then RESD still can attack with equipped monster (you can also use this on RESD equipped monster)
because it's a high level gemini monster with an effect that requires you to have a spell/trap to destroy even your spell/trap cards. Outside of gemini deck, you need to invest a lot to this thing and it runs very slowly.
