I've been saying this for a while and I'll say it again; use this card. I see so many people complain about how relinquished is broken when this card (tbh imo arguably the best s/t removal other than nobleman) exists. It combos so well with some cards, disrupts relinquished majorly making them lose potentially 3 cards of advantage and can allow amazing last turn pushes. USE IT
I agree, this card is pretty underrated. It turns Big Bang Shot into a reliable monster removal, lets you recycle Mirror Wall, may let you protect one of your Spells/Traps from destruction, etc. Not to mention the various benefits from temporarily removing an opponent's Spell/Trap. Oh, and it's cheap from the Card Trader. Pair with Pegasus's Mind Scan skill for even easier use.
Tbh gravelstorm is probably the best backrow removal card in the game. Some people may argue that Twister is but the versatility of this card is far greater than that of Twister, De-spell, Spiritualism, etc. it may be a slow card, that being a trap, but it can easily be used as more than just a card thats used offensively. With the game being heavily revolved around equips and ramming over your opponent's monster, this card can easily prevent that by getting rid of those equips temporarily and allowing a quick push for game
