If Elemental Appeal was kicked, it creates a 7/1 token with trample and haste that gets +7/+0 until end of turn. It doesn't create a 14/1 token. This matters in case something copies that token (the copy will be just 7/1), or in case Elemental Appeal is somehow cast during an end step (in which case the +7/+0 lasts just for that turn).
