If you have a tight budget do the following:
Cl cards with Kelya and Death sum -1 mage -1 hp, cheap cards in general. Trying to bring sum to level 3 4 and rent or buy the cards you need. Slowly accumulate power. After 7/9 months you could be able to have power for higher silver.
Most important side if you are on a tight budget. Write on hive, get around the community, share your experiences. Participate at the weekly events of @splinterlands they do a weekly challenge where they treat you with some dollars. Buy low sell high if you can and keep accumulating.
