Replace Leech Seed with Shadow Ball on Venu, Focus Sash and possibly Ice Shard over Night Slash on D. Scyther, get an Ability Capsule from Murk Forest for Hustle.
On D. Gren, Specs/LO with Flamethrower/Fire Blast, Giga Drain/Energy Ball, Overheat/Focus Blast/Dark Pulse, U-Turn.
Muk likes Leftovers, what type is it’s Regurgitation? Remove Magnitude for Drain Punch, and Minimize is OK, but don’t use Minimize if you opponent has EQ, I would get Knock Off/Poison Jab/Rock Slide/Rock Tomb. Stealth Rock is a support option.
you can use delta gardevoir and delta hydragon because they are very good. you can also teach the haxorus heavy slam, ice fang and crunch insted of aqua jet and iron head
honestly imo iron head+water veil is better than heavy metal+heavy slam, because of the iron head flinch chance, the immunity to burns, and the amount of heavy legendary mons that make heavy slam less useful
No. D. Gard is outclassed by D. Scyther as it has less good MUs. Iron Head is always better than Heavy Slam due to consistency and the fact he doesn’t have Heavy Metal. Ice Fang wants Strong Jaw so no. Same with Crunch, Aqua Jet is actually its best water move. Anyways, if you wanted coverage, EQ, Knock Off, Superpower or Rock Slide/Stone Edge are better.
but delta hydragon with hyper voice and choice specs or life orb is still amazing and if you are ok with adding a non delta to your team then you can add a mega khangaskhan since with the help of mega khangaskhan. I was able to defeat the later Boss battles with nyx, adum and and reukra easily using return, crunch, power up punch and drain punch
