Beza, the Bounding Spring

Offspring 2 (You may pay an additional 2 as you cast this spell. If you do, when this creature enters, create a 1/1 token copy of it.) At the beginning of combat on your turn, target Mouse you control gains your choice of double strike or trample until end of turn.

At the beginning of your first main phase, add R or G for each Raccoon you control. Whenever you expend 4, you gain 3 life. (You expend 4 as you spend your fourth total mana to cast spells during a turn.) Whenever you expend 8, exile the top two cards of your library. Until the end of your next turn, you may play those cards.

As Three Tree City enters, choose a creature type. T: Add C. 2, T: Choose a color. Add an amount of mana of that color equal to the number of creatures you control of the chosen type.

(Gain the next level as a sorcery to add its ability.) At the beginning of combat on your turn, put a +1/+1 counter on target creature you control. G: Level 2 Permanents you control with counters on them have ward 1. 3G: Level 3 If you would put one or more counters on a permanent or player, put twice that many of each of those kinds of counters on that permanent or player instead.
