While it can be dealt with cleanly by a Swords to Plowshares, assuming you managed to hit a creature or planeswalker of theirs, they would have paid three cards (Swords, discarded card and creature/planeswalker) for your one (Entomb/Faithless Looting and reanimation spell offset by drawing a card)
Trying to race a menace deck is a viable strategy if you can play aggressively enough

There are some very strong cards from that deck that I would have loved to add, but I'm trying to stick to a budget here, and they just don't fit
Urza players would be delighted to play this card in the Gruul color combination, alongside such cards like Green Sun's Zenith and Unwinding Clock, which untaps all those artifacts back and allows Meria to generate mana further on
Even if you have 4 dudes to tap, you only get to activate this ability once per turn, per card
