3 resources for a single tough card is way too expensive, but if you're at the 2nd (or 3rd) villain stage you probably want a 3-resource event to actually make progress, rather than stave off one round of attacks. I find that I usually want to just damage the villain's face down to zero once the heros have set up their tableau.

A stun based protection could replace tackle for this and get some heals to become very versatile. This card is one of the only buffs and it is quite powerful compared to toughened or first aid. — zephyr100 · 19
On Expert mode scenarios this gives you two tough cards right off the bat, which I think makes it a reasonable include for green decks that don't actually want to defend. Spending 2 cards to negate a villain action is pretty standard. — OrionJA · 4
