Sandsteppe Mastodon
Creature — Elephant
Reach
When this creature enters, bolster 5. (Choose a creature with the least toughness among creatures you control and put five +1/+1 counters on it.)
A mastodon's path always leads to an oasis.

Bolster itself doesn’t target any creature, though some spells and abilities that bolster may have other effects that target creatures. For example, you could put counters on a creature with protection from white with Abzan Skycaptain’s bolster ability.
