New Zyra Passive Idea

Hello everyone. I'm here to show my New Zyra passive that I thought of in my own time and I hope you like it. If something dosen't make sense or is confusing leave a comment and I'll try to explain. Thank you.

Passive: Whenever one of Zyra’s plants dies, Zyra can walk to the dead plant and within the range Zyra can activate rampant growth to revive that plant and have it fire one skillshot thorn that deals true damage to every enemy it passes through and heals Zyra for 15% of the damage (may change). True damage 100-280 (90 +(10 x Zyra’s level), 900 range (may change). When you cast rampant growth on the pant it replaces the ability with the skillshot ability and not allowing you to place any seeds until you activate the skillshot. If Zyra revives two plants just imagine the skillshot like Lulu’s glitterlance.
