I expect this card to behave a bit like Forked Bolt.
This is a huge bonus with the ferocious trigger. It took shock and made it Vintage-playable.
Get FOILS now around $5-$6 and hold for 2+ years. I see these up near $20 after two growth stages taking something on the order of two years.
Non-foils are likely a good pick-up under $2.00 each right now, but I would focus on a the far more eternal version of this likely eternal card. There will be no post-rotation lull for FOILs of Wild Slash, though non-foils might dip back to just above $1.00 before beginning a long-term ascent (until their first reprint).
