BEGINNER-EXPERT: An excellent starting point for new players looking to learn and build their first decks, and for experts looking to bolster their collection and search for hidden gems.
River Kelpie Primarily a payoff for mechanics like persist or undying, River Kelpie provides card advantage whenever permanents enter the battlefield from the graveyard
For example, if you put Twenty-Toed Toad onto the battlefield and then put Spellbook (an artifact that says you have no maximum hand size) onto the battlefield, you would have no maximum hand size
If that creature is a legal target but the other creature isn't, you'll still put the +1/+1 counter on the creature you control
Or have you primarily created and sold your own work
Whenever a creature with power 2 or less enters the battlefield under your control, you get to draw a cardbut only once per turn, so timing matters
