Otherwise, put it into your hand. Putting a card into your hand is nice, but you can literally win games by just combining Meren with Spore Frog, which you can sacrifice to prevent all combat damage for a turn - and only costs one mana
Im not going to tell anyone how to have fun here, and I respect Serge a lot and in his playgroup, perhaps they enjoy tight gameplay that gets them through lots of turns quickly but 45 minutes seems woefully inadequate
Honestly, looking at the card alone, it's not a card that can be used extensively, but the parts for life-gain decks themselves are available in the Standard environment, and I think it's possible to adopt it in a form that combines Orzhov sacrifice themes
