Ralts!

Dear, dear Brian:

C'mon man. Evolve that thing and stop being silly.

It's worth powering with 14 attack, even if it means it is unable to hit a breakpoint for Confusion that a 15 attack IV Gardevoir can.

It shouldn't be a big deal because Confusion is a slow and high damage move, and +1 damage to your quick move makes a bigger difference to low damage and/or fast moves.

For example if Confusion normally does 25 damage and one with 15 attack does 26, that's only a 4% increase in Confusion's damage, and +1 damage every 1.6 seconds or +0.625 DPS, while +1 damage on a fast and low damage move such as Fury Cutter, if Fury Cutter does 2 damage, +1 damage is a 50% increase in damage, and +1 damage every 0.4 seconds is +2.5 DPS.

Literally the best possible non 15 attack you can get, and it's at a decent level too. I would stick with that one.

If you have regular cloudy or windy weather you could wait to see if you get a Ralts at a higher level. Very low chance to find one with better IVs though.

Also, there is the standard reply for Ralts: If it is male, you can also consider holding onto it for a Gen4 Gallade which can only evolve from a male Kirlia.

If you have the dust and candies to power it up now, I’d do it. If not, I would wait until you do. You may end up catching a high-level weather-boosted one before then.
