- 17 April 2020To determine the total cost of a spell, start with the mana cost or alternative cost you're paying, add any cost increases, then apply any cost reductions (such as that of Tentative Connection). The mana value of the spell remains unchanged, no matter what the total cost to cast it was.
- 17 April 2020Once you announce that you're casting Tentative Connection, no player may take actions until the spell has been paid for. Notably, opponents can't try to change whether you control a creature with menace.
- 17 April 2020Tentative Connection can target any creature, even one that you already control or that is already untapped.
- 17 April 2020Tentative Connection is unaffected if you no longer control a creature with menace after you've cast it. You won't have to pay an additional {3}.
