Eriettes Lullaby is a removal spell that does not go into every deck, so I was a little bit hesitant to include it in the top 5, but the gain 2 life did push it over the line for me
Once a creature that has reach because of Sphere Grid's last ability has blocked a creature, removing all +1/+1 counters from that creature or causing Sphere Grid to leave the battlefield won't cause that creature to stop blocking
At three mana, a 2/3 vigilant flyer is a good rate, and her ability is pretty strong
Both Ruin Raider and Fathom Fleet Captain make blocking necessary for an opponent, forcing them into situations where they might rather not make a tradeor you can surprise them with removal of your own
Lorcanas didnt make enough to meet demand of its initial release, The First Chapter
I'm actually kind of partial to this one, from Throne of Eldraine : This card sees relatively little play in Standard, somewhat outshone by Glass Casket
