#10 Gemhide Sliver (Extended Art) Gemhide Sliver Secret Lair Drop Series, Rare A popular Sliver that was a valuable hit as a Secret Lair bonus card is Gemhide Sliver, as it plays a pivotal role in any Sliver strategy since it turns all Slivers (even tokens) into mana-generating creatures, allowing you to tap your Slivers for a mana of any color
Plus, if you lose even a handful of creatures it has the means of replenishing your hand incredibly quickly
That paired with its three colors means it is likely to be played, at the earliest, turn four
However, in most cases, having at least two lands in your initial hand is the sweet spot for most decks to operate at a decent pace
