Reach (This creature can block creatures with flying.)
{2}{G}: Return Vivien's Jaguar from your graveyard to your hand. Activate only if you control a Vivien planeswalker.
If a Vivien planeswalker and Vivien’s Jaguar are both dealt lethal damage at the same time (most likely in combat), they’ll be put into their owner’s graveyard at the same time. You won’t be able to activate the last ability of Vivien’s Jaguar before Vivien leaves the battlefield.
