Knight of the Dark Ridges

Lifelink, intimidate
At the beginning of your upkeep, each opponent loses 1 life and you gain 1 life. Then, if you have 30 or more life, you lose 10 of it. If you do, put 2 +1/+1 counters on Knight of the Dark Ridges and you get a Siphon enchantment token with "At the beginning of your upkeep, each opponent loses 1 life and you gain 1 life.".
