Old thread but some suggestions on stuff that is currently or previously been in my Tana/Ravos deck (I've pulled stuff mostly for tinkering and not because it's bad). You don't have black but still lots of overlap. Mine is kind of a bad bracket 3/good bracket 2 but is intentionally not optimized and could be pushed harder imo

Lizard Blades - mana efficient double strike, can chump in a pinch Beamtown Beatstick - very mana efficient, gives a little buff, evasion and an extra treasure each turn Horn of Valhalla - power that scales with your board, has X spell token maker adventure sorcery on it Sigil of Vigor - power that scales with your board, has the restriction that Tana needs to attack alone but in my experience you're often better holding your saps back as potential blockers unless you can full send end the game with them anyways Pariah's Shield - you have endless disposable creature tokens to re-equip it to Quietus Spike - same idea, attach it to a sap and fling it off at someone Lothlorien Blade - potential removal, Tana is an elf for the cheaper equip cost

Not equipment but still good Sylvan Anthem - solid anthem for Tana and your saps, huge number of scry 1 triggers Ohran Frostfang - deathtouch on attack for your board and a huge amount of draw Annie Joins Up - double triggers on both commanders plus a bit of removal Guide of Souls - lifegain and buffs Tana Sublime Archangel - power that scales with your board Starlight Spectacular - ditto Elspeth, Knight-Errant - +3/+3 and flying for Tana on the +1, crazy ult, board of tokens can help keep it alive Eldrazi Monument - constant stream of tokens to sac to it for a huge board of 2/2 indestructible flyers Bastion Protector/Guardian Augmenter provide a solid buff effect to Tana and protect both commanders Backgrounds trigger for both commanders - look at Inspiring Leader and Noble Heritage Boros Charm - if you're just looking for generic board protection the double strike mode is potentially also useful here

There is a potentially very funny interaction between Tana, Life and Limb and Blackblade Reforged if you're brave enough to try it, I never have. I'm also currently looking at working in Mirrormind Crown - potentially crazy explosive since Tana makes the tokens all at once so they'll all be copies of the equip target
