Bonded Mate

Bonded Mate acts as a Wall with Defender until it or one of its tokens is the target of spells, abilities, or attacks. Towards the creature that targeted it Bonded Mate then acts as an X/X creature with First Strike and Trample where X = # of turns it has been in play + # of tokens under its control. For all other purposes Bonded Mate is still a Wall.
Each turn it places one {u/r} 1/1 token into play with the text “add +1/+1 whenever Bonded Mate adds a token to the board”.
