Blue Streak of Vengeance

There are two terms for a group of tigers. First, a streak refers to a female tiger and her cubs. Second, an ambush of tigers is a grouping of adults who will, very occasionally, come together to either allocate or hunt for resources.

As an Avenger, Tigra has access to some strong Leadership and Basic cards in Marvel Champions. Her hero kit places a priority on readying, which also fits a number of these cards. This is a large 50 card deck, but she'll be cycling through it fairly quickly.

First, attach Avenge Me to allies for even more card draw than she has in her baked-in hero ability. This only triggers when an ally is defeated, not discarded, so there's no synergy with You Got This! but it's still a great tactic to boost Tigra's ATK then ready her to attack again.

In alter-ego, use Suit Up to find an ally and a copy of Avenge Me. Put Honorary Avenger on Tigra so that Greer Nelson can play Avenger-restricted cards in AE. Additionally, Jarvis adds +2 to recovery or eliminates a status card to keep Tigra at a higher tempo.

Avengers Assemble! readies the whole crew, including Tigra, possibly leading to a defeat by consequential damage of an ally or two with Avenge Me! attached. Use Black Panther to find the one copy in discard and hold it until ready.

Avengers Tower and The Triskelion bring the ally limit up to 5 (Stinger is the secret 6th). Mighty Avengers boosts the output of every ally, including when coupled to Tigra using You Got This!

Lastly, Earth's Mightiest Heroes can toggle any mix of allies and even ready Tigra yet again.
