Gizmek Yata can help extend field presence in a Gravekeeper deck without affecting their ability to Special Summon because they are all Spellcasters. The additional Normal Summon can be used to summon Headman for more swarming, or Spiritualist to make Supernaturalist.
Most Spirit monsters cannot be Special Summoned so Gizmek Yata’s extra Normal Summon helps them swarm the field. Additionally, Gizmek Yata can stay on the field so you have field presence in a Spirit deck. Amano-Iwato is a good monster to Normal Summon with Gizmek Yata’s effect to turn off all monster effects for the rest of the turn.
