TyraniBOAH (quiet +spatk,-spe) EVs= 252hp/52atk/176spatk/28spe
Ability = Sand Stream @leftovers
Ok lemme tell you how this set works, its a big legend basically. The infamous TyraniBoah set. It's basically hell when you met this tyrant since the A/D/V days, its still pretty effective in todays metagame. Ok, the plan is simple. Bring it to something that can't threaten tyraniBoah, set up a subsitute, and watch it wreak havoc. With 404, tyranitar can set up 101 substitutes, which is useful, because blissey has to use 2 seismic tosses in order to break a sub. Once a sub is up, tyraniBoah could fire up some powerful focus punches, OKOing blissey and heatran, and most 2KOs too! Crunch can be used, nailing ghost types such as jellicent and gengar. Dark Pulse could be used to hit phyiscal walls effectively. There are two options for this set basically, Flamethrower can hit steel types such as ferrothorn and forretress which is pretty nice because tyraniBoah is cool like that. You can use ice beam to hit other ground or dragon types such as switch-ins salamence and gliscor.
Checks and Counters
Mainly fighting types such as infernape or lucario wall this set because fighting types are a threat to Boah. Garchomp could also wall this set with a choice banded earthquake, OKOing boah. Scizor can kill off this set with a choice banded uturn, bullet punch, or superpower, which scares off boah, unless boah is in a sub. Basically, anything super-effective walls this set.
