Well, I guess we can thank that print that the lifegain of this hammer doesn't stack anymore.

For anyone wondering, here's how it came to be this way:
- The original print from Mirrodin used a triggered ability to cause lifegain, which was usual during that time.
- Ninth Edition was the first time this card got reprinted, rightfully as a rare this time. The wording didn't change.
- Then Tenth Edition came, and it was decided to turn the trigger into the keyword "lifelink".
- Then M10 rule changes kicked in, turning lifelink into a static ability, meaning the old trigger wasn't lifelink anymore.
However, unlike most cards that got their Oracle reverted from lifelink to their original wording with the triggered ability, Loxodon Warhammer stayed this way since the latest printing... (see all)
