id say a tank
im useing my togakiss as a special tank and it works out great
im useing a modest one max ev'd in special defence 104 in HP and 152 in special attack
its movest (my togekisses moveset) is :
nasty plot-great boost
psycho shift-usefull egg move but im thinking of witching it cause status problems arent so common anymore
air slash-great STAB
aura spheare-great coverege
im thinking of switching the move psycho shift to wish or mornning sun (breeding another one) or thunder wave
but togekiss also makes a desent sweeper
a good moveset can be :
air slash -STAB
aoura spheare-coverege
psychic/thunder wave/megical leaf/ancient power/wish/nasty plot- heal , paralize ,boost or attack hard your choice
extrasnssory/thunder wave/megical leaf/ancient power/wish/nasty plot-same thing here
to answer clearlly id say he works better as a special tank and i will recommned that but it is a good sweeper but still i like tank better
