For the good of this tournament, I very strongly suggest you ban Starmie. It has no reliable counters in this metagame and little to no checks outside of perhaps Venusaur, Vileplume, Lanturn, Lapras, Ludicolo and Exeggutor to a degree. Keep in mind these are not counters, they are simply checks, because none of these Pokemon like taking the wrong hit repeatedly. Normal types such as Snorlax and Blissey are very reliable counters in standard meta because of their defensive typing, having no special weaknesses at all. Starmie would be extremely boring to have present in this metagame and would easily dominate. It is literally the single-most powerful Pokemon without the presence of normal in generation 3. Its massive coverage, speed, and power are just too much to handle.
