Though being able to pump out a solid token each turn is good, it's pretty exciting to see an ultimate loyalty ability that can be activated after one turn even if that ability can be underwhelming
Phelia is amazing in many situations , effectively removing a blocker , generating a 3/3 token with Blade Splicer , and flickering key creatures like Elite Spellbinder
The Lord of the Pit required you to sacrifice a creature each turn, which is a significant downside, but Timmies embraced the card, I believe, because the idea of a pit demon that required constant sacrifice was cool enough to override the downside
If an artifact or creature spell is countered this way, put that card onto the battlefield under your control instead of into its owner's graveyard
Honestly, most of the flipwalkers from MH3 are semi-broken, but Ajani, Nacatl Pariah is just unreasonable
The most aggressive versions of U/G Merfolk probably wouldnt want to play Seafloor Oracle, but a token version that is looking to play a longer game with Deeproot Waters and Jungleborn Pioneer could be looking toward this card for card advantage
