Remember that #nextspell takes effect on the square where the mainspell lands. So the maineffect should be something the caster throws on himself. So if you want to make a battlefield spell that summons something awesome while killing the caster, I'd do it by this:
Gem-costing personal buff -nextspell-> massive damage on caster -nextspell-> Summon

If you want the banquet effect for a ritual spell, perhaps you just should copyspell it and change damage (summon different creature)?
