Youkai are also quite fragile. A good number of them can be utterly destroyed in a single round, not to mention that one of Magic Gunner's bullets can de-summon Youkai quite easily. If Fast Offense didn't exist, you'd be hard pressed to see a Summoner actually summon.

This is not true. A slow Summoner can easily get their Youkai out for next turn, due to some Youkai's silly base Celerity, which means they'll go before anyone almost as a certainty. Yes, most can be destroyed in a single turn, but even the squishy ones boast 500 HP, which the Summoner himself isn't receiving because of the greater threat on the field, of which two can be summoned in one turn.

Magic Gunner is an issue via its shells, aye, but it doesn't stop them from chunking the Gunner if used through the above-mentioned method.
