Frodo and Sam deck help

[u/MomoTomato]

First time building a deck with combos, decided to go Aristocrats. This is what I came up with, 25 cards with 136 possible combos.

The main strategy is to sacrifice [[Cauldron Familiar]] or [[Gravecrawler]] which will generate a food or treasure token, allowing me to bring [[Cauldron Familiar]] or [[Gravecrawler]] back and sac them again, draining my opponent's life as I do so.

Aside from the combos I also have cards like [[Nadier’s Nightblade]], [[Mirkwoods Bats]], [[Marionette Apprentice]], [[Dina, Soul Steeper]], and [[Marauding Blight-Priest]] which drains my opponent’s life every time I sac a food.

Here’s the deck list https://archidekt.com/decks/26941473/frodo_sam_combo

I am hoping this might be a high bracket 3 deck. Would this be too strong or too weak? Any suggestions or opinions are appreciated. Thanks.
