I need some opinions on this moveset:

• Spikes
• Destiny bond
• Toxic
• Protect

This is what I am looking at and I'm wondering if there's anything I should swap out for. I've considered minimize but that would just mess with destiny bond.
Seeing how none of these apply to attack base, I would just have a max speed. What other stat(s) should I put the rest of my evs into? Do I cater more towards destiny bond or spikes? One wants me to live more, the other to die. Maybe I should maintain a speed and defensive spread?

I would suggest swapping Protect for Surf. Then you aren't completely locked out by Taunt and Protect doesn't gain you much anyway. For evs, definitely do max Speed. Next, either use max HP for more Spiking, or max Sp Atk if you wanna be a bit more offensive and get to destiny Bond use faster.
