Hello! What do you think about combo: Mirror Gallery + Minion Reflector + Etrata, the Silencer ?

After Googleing what the Legend rule is, I think I want to do that. It'd give 2 of the 3 counters I need to win

Based on my own experience in multi-player format I can say that you definitely need more board wipes: Damnation , Languish , Ritual of Soot , Cyclonic Rift (one of my favorite), Evacuation , Toxic Deluge or Black Sun's Zenith (to deal with indestructible creatures) etc. The choice depends on your meta. You also need tutors: Vampiric Tutor , Demonic Tutor , Diabolic Tutor etc. Dimir Signet , Dimir Keyrune - for mana stabilizing. I recommend to take out Unmoored Ego - it seems useless in EDH. Some ideas for card draw: Phyrexian Arena (classic!), Necropotence (a great card believe me), Twilight Prophet (I'm crazy about this card in Standard and I think it has a great potential in EDH), Doom Whisperer (another great card from Guilds of Ravnica). Good luck in brewing!

I looked at all of those suggested cards (None of which I have), and I think I may have some sort of substitute for a few of them. I'll see what I can do, thanks

I would diversify the land base. Also some spells like Lich's Caress are quite mana-expensive.

Another fun card with Etrata is Helm of the Host . If you put Mirror Gallery in your deck as suggested you should consider Rite of Replication . This card is realy funny in commander.

I agree with DRmagic2017 that you should put in some board wipes and more mana fixing. The tutors are not a must have in a deck. They are very good but you don't have to put them in a budget deck especially if the other players in your playgroup don't run them.

Okay, so I have non of these cards that were suggested but I'll go to my local Good Game and see if I could get some. Thanks for the all of the help guys
