1 have one monster (dark), opponent have 2 monsters (water and machine), I set this trap before, its not activated. Why it didn't work? Then the next turn, I destroyed the water monster, so I have 1 dark monster and opponent have 1 water monster, its still cannot be activated (the field didnt have set monster), anyone can help me?
1. water and "machine"? what attribute is that machine monster?
2. if each of you already have exactly 1 attribute, so there'a nothing able to destroy. you can't activate it obviously. it don't limit so there's only 1 attribute on the field.
Good for OTK I guess.
You can remove monsters on your opponent's field while you control 2-3 monster. With your opponent controlling just 1 monster, your other monsters can now do a direct attack (meaning full ATK damage) after that 1 monster is destroyed by your first attacking monster.
*obviously, you swarm the field AFTER you use this card, not before. Would be stupid to swarm the field before using this card, unless it doesn't matter for your advantage (for example, controlling 2 Carrot with 2 Plants in hand)
Good against Six Sams and Gladiator Beast, and Sylvans somewhat got hit by this too.
