On its own, Medomai the Ageless has some exceptional abilities
Right now I have it in so that I have something good to return with The Mending of Dominaria, but maybe a better plan is to use Bone Dragon and not The Mending of Dominaria, either just relying on Devious Cover-Up or possibly using Bone Dragon to sculpt your graveyard for Gaeas Blessing, though that sounds like the kind of late-game nonsense that will never actually come up, whereas Gaeas Blessing messing up your Bone Dragon will come up
It may be better to actively take advantage of the high RBI that can receive dual support rather than expecting the effect
We are looking at Grave Sifter, Flash Photography, and Cool but Rude as the weeks biggest gainers are due to broken new synergies in Lorwyn Eclipsed and TMNT
My guess would be that it'll likely be Common and Uncommon cards like the Bidoof above, as I don't think they'd dare do this to, say, a Radiant Charizard
In either case, the key is to look for a moment when your opponent has multiple monsters on-field, then activate your card, Tributing Ame no Murakumo no Mitsurugi
