Loving these cards together in my new deck, but am curious, if i have 2 Hero of Leina Tower and Bioshift them paying x=2 for heroic, does 2 counters get placed on both of them (almost assuredly not), or do I have to pay the Heroic X for both in the cost of bioshift?
Each mana you generate can only be used to pay one cost. While Bioshift will cause each Hero to trigger, they will resolve one at a time.
First, Hero A's ability will resolve, and ask you to pay any amount of mana. You'll place that many counters on Hero A.
Then, Hero B's ability will resolve, and ask the same thing, but any mana you used for Hero A's ability will already have been spent on Hero A's ability.
Then, when Bioshift resolves, you can move any number of counters from whichever was the first target over to the second (in case you maybe misspent mana or other things happened).
