In silver league I still can compete with my level 1 summoners but once I get to gold league everyone destroys me. I am only renting SCARRED LLAMA MAGE level 3. It costed me 3000(?)DEC for a season. I should be able to make some profits but so far I still need 752 DEC to get even. I hope to get something good from chaos legion because staying competitive is getting harder and harder.
Can you use a L3 in silver?
Chaos legion should be decent and it might be worth looking for individual cards on the market after too.
Only in gold or higher.
