If you would get one or more {E} or experience counters, you get twice as many instead.

If you would get one or more counters while you have 10 or more of that type, you gain 1 life and put a +1/+1 counter on target creature instead.

{W}{U}{B}{R}{G}, {T}: Search your library for a legendary creature card with mana value 4 or less that's two or more colors and put it onto the battlefield, it gains "When this creature leaves the battlefield, you get two experience counters." Then shuffle your library.
