So as I was saying, Toedscruel has the exact same stats as Tentacruel. Normally that would be alright, but here's the problem. Tentacruel's stats work because it is water/poison. Amazing typing because that means Tentacruel's only weaknesses are ground (which can be circumvented by being good against), electricity and psychic. The last 2 usually being special oriented, and Tentacruel can tank. Being part poison also gives a poison immunity and makes toxic unable to miss.
Toedscruel? Being grass/ground doesn't work well with Tentacruel's stats. Even with a high sp. def., you take 4x ice damage and are now weak to fire. Both of which Tentacruel resisted. Your only resistances are ground and rock which is pitiful when Tentacruel has 8 resistances. You have an immunity to electric which somewhat helps, but it is not a paralysis immunity. Toedscruel has access to spore which is amazing, but that damned Mycelium Might always makes you go last. Also Toedscruel doesn't have acid armor like Tentacruel. Why is that? A mushroom should have that.
