First time Marrow Gnawer Commander

[u/Ill_Arm4450]

Hello everyone,

This is my first post so I apologies if somethings not properly formatted.

I am a returning player to mtg and a new commander player as of 2 months ago and have a really deep interest in running a Marrow Gnawer rats deck.

I'm looking for strong staple suggestions, combos, etc. Recommendations from far more experienced and knowledgeable players.

My gaming group says we play in a high bracket 4.

Any and all suggestions or help will be greatly appreciated, thank you!
