So I have 2 tier 2 alpha catalyst in my overflow, one's about to expire in 10 days, the other in about 28 days. My question is are any of the champs I have now worth taking to R4. I don't have the material yet to rank anyone else up but the science champs. But I could hopefully get it in 28 days for maybe archangel? And just let that 1 go to waste.
