It is not as good a threat although it does offer some reach but given that it is also half the price, is playable in many more archetypes and is also a mana ramper and fixer The drawbacks of this card as life gain are that it is slow to get life returns from it, it will situationally not work for life when no dead guys are there to be exiled, it is reasonably easy to kill and it cannot give you a big single injection of life
This is a big one that separates Arena from MTG Online and MTGA from IRL play which do offer trades
These are cards that only exist in MTG Arena and nowhere else
Also, note it's power in any deck, but in tempo, aggro with Anthem effects, artifact and dorks matter like Losheen, Hate Bears, Auras, Equipment, Voltron, +1/+1 counters matter and more this is a must kill on sight guy
