Description
You can let a player attack you and take the monarchy, then watch your opponents fight for control of it

The only reason its not rated higher is that dreaded living until your next turn clause can be tricky to pull off when everyone wants to make sure that doesnt happen

Put a +1/+1 counter on target creature

Thats already a great start, but dont discount that attack trigger either
