Sorry for the the bad English D:

These cars are mostly for defense and some control.

Chains itself to another creature of yours. After that, both creatures must have their HP depleted for them to die. if only one reaches x/0, it'll stay on the field until the other reaches x/0.

Both dies after 2 turns

Meatshield Tree: Nice idea, really. Although decide if you want to lower the cost or raise HP on the upgrade.
Tank: Also nice idea. Good balance of cost as well.
Quetzacoat: Maybe don't move the stats and make the ability 2 on base and 1 on upgrade. It seems to be a nibbly creature control, and... why not? Life doesn't have one.
Zaratustra: Particularly powerful, but also situational. Well, such combinations can stay.
Life Cycle: Seems to be a good endgame push thing.
Life Scythe: I'd rather use Quintessence. This one is too costly and not even beneficial.
Flash: Done multiple times before. Your version sounds alright.
Sunray: Also alright. It targets just one enemy, after all, and the effect isn't that powerful.

Now that I noticed... Genesis tree would be too powerful if immortalized. It'll need some "non-buffable" treat

Meatshield Tree: Nice idea, really. Although decide if you want to lower the cost or raise HP on the upgrade.

I'd rather lower the cost them

Life Scythe: I'd rather use Quintessence. This one is too costly and not even beneficial.

That's the thing. It's an 2 turns kill card, it's would be useful used in the enemy (at least I think it would xD)

I know I posted here...

What happens if you chain something to an Armagio with Gravity Pull?  Its not game winning for some decks, but for others its a pretty damned good shield.
