That's pretty great in itself, but the Merfolk Scout also comes with a little bit of card draw and ramp built in
Basking Capybara One generic, one green, Creature - Capybara - 1/3 - Common Descend 4 Basking Capybara gets +3/+0 as long as there are four or more permanent cards in your graveyard
And from time to time, WotC makes a cool commander that buffs wraiths, only for players to find that there are only so many playable wraiths to begin with
If you no longer control three permanents you don't own as it resolves, you won't draw three cards
They should stay on whatever permanent they were on, even though they become permanents themselves
For each die, put a number of +1/+1 counters equal to the result on each creature you control that die is touching
