Calm Nature
- Leech Seed
- Synthesis
- Giga Drain
- Hidden Power Fire / Hidden Power Fighting
Why It's Not Sunkern: This special wall is notable for its extraordinary healing ability with Synthesis and Leech Seed despite the lack of Leftovers or Black Sludge. Giga Drain is its main offensive move, and two of the primary Sap Sippers in the tier who can absorb Ivysaur's other attacks, Sawsbuck and Gogoat, don't appreciate taking a HP Fire, and neither do many Steel types, or Grass types which are immune to Leech Seed. Hidden Power Fighting means Ivysaur loses power against Gogoat but can better harm Bouffalant. As a Grass/Poison type, it is immune to Spore, Sleep Powder, Stun Spore, Leech Seed, Toxic, and being poisoned in general, and absorbs Toxic Spikes on switch-in.
Grotle can be considered the physical equivalent to Ivysaur, though it lacks a Poison typing as well as a reliable counter to Sap Sippers.
