Titania, Protector of Argoth is a pretty unusual card, rewarding a seemingly unintuitive play pattern by giving you huge 5/3 creature tokens in exchange for your lands
Unfortunately, despite the fantastic, vibrant artwork, this card has struggled to crack the $2.50 mark and doesn't show many signs of climbing the list anytime soon
When this card is destroyed by battle and sent to the Graveyard, every Monster on the field except face-up Wind Monsters go with it
You might have a card that's extremely expensive in pristine condition, but if you left it under a couch for years and it's folded in half and dog-eared that value will begin to drop rapidly
In Commander, Bolas fits perfectly into slower Grixis control shells that reward patience
And the maps are way less of a downside
