Ralf Rendel, The Rulebringer

Whenever a non-token creature enters the battlefield under another player's control, you
may draw a card unless he/she pays {1}.
Any spell that targets this creature cost {x} more,
where X is the highest converted power among
creatures you control.
{t}{p/c}{w}{r}:Create a 1/1 red and white Bodyguard
token under your control, if you already have it,
give it a +1/+1 counter instead.
