mtg corona card MTGNexus creatures of the creature type of your choice get +3/+3 until end of turn. MTGNexus - Sword of Corona

This can allow you to deal with an attacking creature an opponent controls and possibly even deal a hefty chunk of damage to another opponent

I dont expect too much of a dip here, but without the reprint itd have crept up over time

You can give any target creature under your control shroud until the end of a turn, but the card asks you to sacrifice an MTG land in exchange

The most important use for Shock at the start of the format will be to disrupt the Saheeli Rai / Felidar Guardian combo that will certainly see Standard play

However, I understand some people do not like playing with joke cards, even in a casual format like Commander
