Emperor Nahkimmi

Council (This creature can have a
partner if the other commander shares color identity)
Whenever a creature attacks you, you may reveal
cards equal to the number of naga creatures you control. For each land revealed this way, prevent
1 damage. If more forests are revealed than the attacking creature's toughness, remove it from
combat. You may put the revealed cards into
your graveyard, If you don't, put them back on
top of your library.
