Beast Wars Transformers Mutating Card Game (1997)

From the box:

The Beast Wars have begun! Choose side. Hand-pick your beasts. Now march them onto the mountain top. Advance . . . Retreat. When you come face to face with the enemy . . . ATTACK!

Victory – and defeat – are in the cards. Use Secret Weapons . . . Energon . . . or Mutate your Beasts into more powerful Robots as you battle to be the first to capture your enemy’s warriors – or drive them over the mountain’s edge!

24 beast cards, 72 battle cards, 3-dimensional mountain top and game board.

Reads for 6 and up on the box. There is a little strategy when playing.

Based in the Transformers Universe.
