If poison-proliferate control becomes a thing, these three cards will absolutely form the backbone of it and be the cards players rely on the most to get the core game plan rolling
I still think firebending is a really weak ability, but if its going to get some use anywhere, making it both feed back into the card its on (by the new spells cast triggering prowess) and scale with each card played beforehand (also because of prowess) is the best possible option
Enchanted creature has "Whenever this creature attacks, if its toughness is 3 or less, put a +1/+1 counter on it.") If you don't choose a target for Protective Parents's ability, the Young Hero Role token won't be created
Goreclaw also gives each Creature with four power or more +1/+1 and trample whenever it attacks
Or you can grab a combo: Karmic Guide, Reveillark, and a sacrifice outlet creature and set up a loop with a single card
Once you have duals you can upgrade your ramp to things like Farseek and Nature's Lore
