Combo help with a hug deck

[Morganator 2.0]

So I'm rebuilding my Kynaios and Tiro of Meletis "specific hug" deck. It's a kinda janky deck but that part doesn't matter right now though.

 What I really need is a second creature-based combo. So far I have Kiki-Jiki, Mirror Breaker with either:

Felidar Guardian
Pestermite
Corridor Monitor

This combo can be built into with either Birthing Pod, Defense of the Heart, Tooth and Nail, or Shared Summons. The downside is that if Kiki-Jiki is gone I have no combo. I have three card slots left (I'm also willing to cut a few other cards) so I'd like to add another creature combo that can be searched with Tooth and Nail as a backup win. Any ideas?

I'm thinking of Rionya, Fire Dancer with Combat Celebrant, as Combat Celebrant also combos with Kiki-Jiki, and Rionya isn't a completely dead card. The third slot could just be Splinter Twin or a flex slot.

If you have any other suggestions please let me know.
