Lots of great cards in Tier 3. Never played Life up until about 6 months ago. Now, it has become one of my favorite splinters.

Shieldbearer is is a great card in lost/weak magic matches. It saves your other monsters (because it has taunt) and has high HP and a lot of shield.

Evangelist is one of my favorite reward cards. At max, it has rust (as the only monster in the Life splinter). It's Inspire ability comes in handy too.

Luminous Eagle is great in combination with Thunderbird. After Thunderbird stuns, the Eagle takes out the enemy monster with its Shatter and Knock Out ability
