Lord and Lady Hardwyn

You cannot cast legendary spells or activate
abilities of legendary nonland permanents.
At the beginning of your end step, if you control
no other legendary creatures, target opponent
gains control of Lord and Lady Hardwyn.
Lord and Lady Hardwyn must block a creature
named Mira Hardwyn, Hired Blade if able.
When it does, you and the attacking player each
lose the game at end of combat.
