So, let's look at Nezahal, Primal Tide as a creature. First of all he's a 7/7 for seven mana. He also can't be countered. He also allows you to have no maximum hand size which is great and control them. Whenever an opponent casts a noncreature spell, you draw a card. That's hand advantage, which is perfect for a control deck.
Also, Nezahal has another ability, which allows you to discard three cards and exile Nezahal and return it to the battlefield tapped under its owner's control at the beginning of the next end step. This allows Nezahal to dodge removal, which is very powerful.
For some time in mid-2018, Nezahal was only retailing for about a dollar. But, in late June, his prices moved up to close to a dollar-fifty. That was important because whenever you see a card move up that quickly, it typically indicates that the card is in extremely high demand. Whenever a card is under $2 and seeing Standard play and is seeing a rapid increase in price, it means that demand is quickly outstripping supply. This means there's going to be a major price change soon.
At that point, major vendors like Card Kingdom listed Nezahal for $2.50. Meanwhile, the cardalso listed on Amazon for around the same price. However, the TCGplayer market took time to catch up. At the time, it was going to be in Standard for quite a while. But, it was clear that it also would see play in Commander. At the time, I said that the ceiling on this card may not be that high, perhaps three or four dollars. Indeed, by mid-2019, it was a $3 card at retail. People that bought in under $1.50 back then are probably fairly thrilled today.
As a player, Nezahal has been a great card to have if you really like to play control. It's also great if you just like to collect Dinosaurs. All in all, it was a good card to have in your Standard collection. Of course, with Rivals of Ixalan leaving Standard in October 2019, what would happen to Nezahal? Fortunately, by the time War of the Spark rolled around, Nezahal was no longer seeing Standard play. Nezahal then became a purely Commander card, which is always good. It also helped that Arixmethes, Slumbering Isle came along from Commander 2018, as that deck loves to have a copy of Nezahal. Other Commanders who have taken a liking to Nezahal, Primal Tide include Jodah, Archmage Eternal, Braids, Conjurer Adept, Azor, the Lawbringer, Raff Capashen, Ship's Mage, and more.
Overall, Nezahal, Primal Tide has been a nice little find for those lucky enough to dig him out of the dollar bin. But, it doesn't look like this Elder Dinosaur is going anywhere. His abilities that give you an unlimited hand and some sweet extra draw power will benefit many Commanders for years to come. I'm happy that I called him as a good investment, as he probably isn't going to disappoint for some time.
