the main argument is that it is guaranteed 2-3 layers plus has a fats taunt to screw over other leads
Not true at all. Very often deoxys-d Will onlyget a signle layer of hazards up. Perhaps oyu are not effective enoguh at dealing with it/ Lead with a banded scizor, banded/scarf ttar, specs latios, any gengar, scarf politoed, and several others and you will find a deo D can only get up stealth rocks. Bastiodon has taunt, magic coat and stealth rocks and STURDY, so he is like 100% rocks. How many bastiodons do you see in OU? And he resists U turn :O
Deo D can even get zero layers of hazards down if bluffed correctly against or by being scarf rachi'd. By leading with something what often has rocks and could be taunt/magic coat bait, only to 2hko it and stop it rocking at all. I find It only gets spikes up after rocks If I let it or im unlucky (Red card switches)
Also I made my own 3 player chess board.
