The sixth card is a support card for Winged Kuriboh. If you have Winged Kuriboh in your graveyard you can pay half your life points to obtain Polymerization or a Fusion spell card, and if you have three of Sabatiel in your graveyard you can banish them to increase one of your monsters atk by the highest atk on the field. Its second effect can either make one of your monsters the strongest on the field, or double its strength, which is great, but its first effect causes some confusion. Going by what I know of Multiply Sabatiels first effect only works with Winged Kuriboh, and not either of its LV forms, but Polymerization and Fusion in the effect text have the same quotation marks around it and it follows that with specifying that Diffusion Wave-Motion isn’t a valid target, which if that needed specifying should mean that Sabatiel would work with the Winged Kuriboh LV cards, and Multiply with any cards with Kuriboh in the title. Either way it seems like a good card to me, if you have a fusion deck then Winged Kuriboh is not bad to use as a wall for a turn, and you can also try and use copies of Sabatiel as fodder for effects like Graceful Charity. All in all it seems like a pretty good card.
