>>46512167I played the old games when they first came out. I like ORAS better, specifically because of the physical/special split.
If we are just talking about the older games, then yeah definitely surf. My first few playthroughs I used muddy water from what I remember because I thought it was a pokemon-specific good move, but upon replaying the games maybe 8 years ago I realised it was trash and started using surf instead.
