1. How to make Zigil Miner work better? Put cards at the same cost into one deck?
2. Exhaust 2 allies you control to shuffle your deck and discard the top 5 cards. Put up to 2 allies discarded by this effect into play under your control.
The total cost of the allies put into play cannot exceed the total cost of the allies exhausted to pay for this effect.
What does "the total cost" mean? Does power symbols matter?
