You literally cant lose with this
As The Great Work, this saga can be a smaller board wipe, dealing three damage to an opponent and all their creatures
WotC usually does that to show different versions of a mechanic at different power levels
(Damage dealt by the creature also causes you to gain that much life.) Rosa, Resolute White Mage Rarity: Rare TYPE: Legendary Creature SUBTYPE: Human Noble Cleric CMC: 4 Mana cost: USD: $10.11 EUR: 5.34 TIX: 0.81 EDHREC RANK: 6482 (2/3) Reach (This creature can block creatures with flying.) At the beginning of combat on your turn, put a +1/+1 counter on target creature you control
An issue with it is that it is neither a threat or an answer
Even if it's only one creature, in dedicated landfall decks, this gives you a guaranteed way to hit all of your landfall triggers each turn, even if the trample is irrelevant
