On creature-heavy decks you should run fewer board wipes because you dont want to clear your own board too often (about 2-3 seem enough, unless they are one-sided where you can add more without hurting your own strategy) while on creature-light decks you need more (about 4-5 is a good number)
Even so, you can be sure that loads of collectors have at the back of their binders a complete set of art cards, as well as other out-of-game extra cards like tokens, checklists, and punchcards
In this deck I've found that Selvala's draw ability doesn't trigger as much as you would imagine, given that most of our creatures end up around 6 power
Solid density, excellent cards at the top
The flexibility is what makes it exceptional it's simultaneously a ramp engine, a card draw engine, and a creature-token engine that scales with your life total
