Tips, related cards, skills
It's best used defensively when your opponent is about to attack with their monster, instead of using this to blindly target their spell/trap cards, which could be cards like Wild Tornado, or Security Orb.
Make sure to also watch for your opponent's monster effects too, cards like Vanguard of the Dragon will benefit from being destroyed by card effects.
Needle Sunfish's effect will activate when it gets sent to the graveyard, making it one of the better cards to use Fish Depth Charge with. It's better to not activate Fish Depth Charge to destroy your opponent's monster if they only have 1 monster on the field, because this will waste Needle Sunfish's effect.
The point is that water decks rarely carry enough normal monsters to make good use of otc, so this is a welcome variation on the idea that should work rather well with water decks, especially since it is easy to swarm the field with weak effect monsters.
You guys realize this steroided fish to charge is leagues better than the small guppy order to charge. Sure the tribute window is smaller ( fish vs normal monsters) but this can destroy any card AND draw cards
So Needle Sunfish is going to see more play in Mako decks now?
