This would be a good enough effect on its own, but take note: Swords to Plowshares is an instant , meaning that it can also be used offensively to interrupt your opponents key plays
They cost four mana, can be played for free turn one with an opening hand grip, and then typically are good solid value for four later, but rarely broken
At the minimum six mana you can either draw three cards, have an opponent discard three cards, or give your creatures +3/+0, trample, and haste until end of turn
Even the bad cards are exciting to find, especially if youre a master set collector like me, filling binders with one of every card in each set
