During damage calculation in your opponent's turn, if this card is being attacked: You can target the attacking monster; make that target's ATK 0 during damage calculation only (this is a Quick Effect). This effect can only be used once while this card is face-up on the field.
After reading this evaluation I stopped believing in this websites proficiency about other cards. "Blue-Eyes White Dragon is better than this card in terms of stats, and you will not use this card." Really? Seriously?
"BEWD is straight up better than this card"
Uh, no it's not. Even with support, Blue-Eyes dies in a straight battle to stronger monsters. Suijin can, once while it's face-up, destroy anything in combat without spells or traps.
Check out how to build a deck with this card!
I've got a deck completely based around this card: unshaven angler to and the spell that summons 2 tokens, then set suijin, use spells to boost his def and wait for the enemy to attack, then you can reduce enemy atk to 0 and deal up to 4700 damage
Ive killed off 6500 ATK BEUD before with suijin. BEWD is nothing compared to BEUD lel
LOL the descrption of this being compared to BEWD when this card has it's own niche. Besides working as an ambush attacker, it works as a staller, because your opponent literally can't attack this card unless they're prepared to lose 2500 LP.
Why is this card being compared to BEWD? What's the point? Suijin (or the other trio guardians) is not an upfront powerhouse card like BEWD, I believe I used it more as an ambush LP reducer, with great results. Usually, opponents (either AI or real player) are rather impatient, they'll attack everything, and that's where Suijin comes in (SET in the field). Instant minus 2400 LP (2600 with Umi), and what's more it gives momentum since the attacking monster will have no choice but to remain in that position until the next turn.
