Without TMs, Blastoise's movepool is bare bones. With them, you get Normal and Dark coverage and more on top of Hydro Pump and Surf for STAB. The natural kit handles basics, but TMs are doing the real work.

Blastoise Yellow Guide
In Yellow, Blastoise has a 510 base stat total and ranks as C-Tier: a niche pick in Yellow's meta. It works best as a balanced. Blizzard anchors the moveset.
Mega Evolution isn't available in Yellow, but Blastoise does have a Mega form in Gen 6-7 games (X/Y, ORAS, Sun/Moon). Mega Blastoise hits 610 BST.
In Yellow, Blastoise fills the balanced role. It's a special attacker with base 85 Special. Base 78 Speed is workable. Faster than some, slower than many. And it's enough bulk to take a hit or two.
In Yellow, run Blizzard, Hydro Pump, Body Slam, and Surf on Blastoise. Blizzard is the most common pick at 0% usage. Surf provides reliable STAB damage.
Game Availability
Blastoise first appeared in Red & Blue and spans 21 games across 10 generations. It later gained a Mega form in Generation 6 and a Gigantamax form in Generation 8, adding new dimensions to its competitive identity.
