- 23 June 2020Stone Haven Pilgrim gets +1/+1 just once, no matter how many artifacts and enchantments you control. It doesn’t get +2/+2 if you control an artifact and an enchantment.
- 23 June 2020If you don’t control an artifact or enchantment immediately after Stone Haven Pilgrim attacks, its ability doesn’t trigger. If you don’t control one as the ability resolves, it doesn’t get +1/+1 or gain lifelink. It doesn’t have to be the same artifact or enchantment both times, however.
