Can Rell use her trigger to equip Spinning Axe from hand for free, ignoring both energy and power costs, even though her ability restricts playing Equipment with energy cost no more than 2?

Ruling: Yes, Rell can play Spinning Axe from hand using her trigger, ignoring both its energy and power costs. The restriction "with Energy cost no more than 2" only checks the printed energy cost and does not prevent playing cards with higher power costs.

Sequence:

• Check if Spinning Axe meets Rell's energy cost restriction (2 or less printed energy)
• If yes, Rell's "ignore its cost" effect sets both energy and power costs to 0
• Play Spinning Axe for free

Nuances:

• The restriction "with Energy cost no more than 2" is a targeting/eligibility requirement that only looks at printed energy cost, not power cost
• "Ignore its cost" without specification means ignoring both energy AND power costs
• If an effect only ignores energy costs, it will explicitly state "ignore its energy cost" (like Jayce or Fizz)
