Many of these cards will be added to some effect, such as discard or counters, and many of these cards have a focus on specific card types
I can't see paying 6 mana and losing half your lands to make your lands tap for 3, unless you're doing like a High Tide style combo, or know you can just replay the lands from your graveyard (and want to get the land triggers again)
If you just want to open packs, please, for the love of the Grand Line, buy a standard reprint box and save yourself about 90% of the cost
Faithful Mending Faithless Looting has long been a staple of graveyard-based strategies and Faithful Mending extends that value further into the color pie
Thank you in advance for your understanding
, : You may play the exiled card without paying its mana cost if creatures you control have total power 10 or greater
