The best theoretical typing in turns of number of weakness and resistances, other than ghost/dark which has no weaknesses but few resistances, would be a ghost/steel pokemon with levitate. It would have 4 immunities, one weakness, 4 sources of neutral damage, and 8 resistances
The fact that it's ability needs to be levitate just to remove a weakness isn't very good.
Cledinja is best defensive poke EVAR
that or a Cledinja with ghost dark, which could not die ever, excluding struggle --- Louis: When things go back to normal; Zoey, Bill, I'm giving you both jobs. Francis, Imma teach yo ass how to read! ~Left 4 Dead
don't passive forms of damage (sandstorm, hail, etc.) hurt pokemon with wonder guard? cause i was playing XD a while ago and a sandstorm took out 'ol sheddy for me --- We are here to make coffee metal. We will make everything metal. Blacker than the blackest black, times infinity.
Yes. But Cledinja is a mix of Shedinja and Clefable; which means it also has magic guard which completely ignores the bane of Shedinja. If Wonder Guard doubled as Magic Guard, Shedinja would probably be uber. --- Louis: When things go back to normal; Zoey, Bill, I'm giving you both jobs.
