Cacti-covered Bull

Thorns 2 (Whenever this creature is dealt combat damage by a creature, this creature deals 2 damage to that creature.)
When Cacti-covered Bull attacks and isn't blocked, if you control a Desert or a Desert card
is in your graveyard, it gets +2/+0 until end of turn.
Although cacti-covered beasts share a lot of similarities with cacti, one thing they don't share is the mobility.
