In a The Gitrog Monster deck, we do this by sacrificing lands, using Life from the Loam to return them to our hand, and then playing them again, or by using cards like Scapeshift and Nahiris Lithoforming in conjunction with Splendid Reclamation, but I wanted to return lands to our hand from play, and you know what card does exactly that
That isn't stopping players from valueing these cards highly, as they're a bit of a collector's item since they're not very popular
Chainsaw Insect plays similarly to Jirai Gumo - big damage, big drawback
Hieratic Dragon of Gebeb
Do keep in mind however, that you cannot Summon from the Extra Deck as long as they remain on your field
In the past few years, the trading card market has exploded and everything from baseball cards to trading cards are selling like wildfire through online marketplaces like eBay
