Point taken.
Well, I have an idea on a fairly odd effect.
What if we made use of "Spear fragments"?

Due to lack of space on the card, I will tell you now. Fragmentation destroys Diamond Spear, deals 5 damage to the opponent, and creates 3 Spear Fragments.

This means, over time, you can create an army of flying Diamond Spears, all from a single card in a mono-

with a

splash!
