Now THAT is a cool ability. It doesn't even count his counters, just his power, so you can give him equipments, enchantments, temporary boosts etc. and get powerful creatures. Theros gave us plenty of cards to scry, so you can plop things on the bottom of your deck with ease!

Good ability, but I wish he had a cooler name. His name is just "Krenko" with the K's changed to a G and a Z.

I really love this card! its all the fun of Cellar door and more! With things like Tel-Jilad Stylus, Reito lantern Soldevi digger and junktroller. you can set up the bottom to be more of what you want! And if you want to have some real fun Goblin Charbelcher Mindmoil and Teferi's puzzle box can set you up for Alot of awesome combo's. It is also Very nice that his ability does not care about Graveyard hate! all in all good card. well made and fun! 5/5.

Captain Lightbound is incorrect. Grenzo does indeed fold to graveyard hate, and folds to it very hard. Grafdigger's cage, rest in peace, and leyline of the void all punch Grenzo hard. He is immune to pinpoint hitters though, like the one zombie cleric and scavenging ooze. (grenzo's ability will activate all at the same time, leaving no room for an opponent's response.)

Works wonders in Lord of Riots EDH alongside Maga, Traitor to mortals, and also works excellently with goblin swarm tribal.

I always love seeing red generals that combo with Braid of Fire. (Braid of Fire is my favorite card)

Adding white, you can use Mistveil Plains to repeatedly reanimate your creatures.

Actually, Rav0004, his ability will only fold to Grafdigger's Cage of the cards you listed, and also Wheel of the Sun and Moon for cards you didn't list. This is due to the fact that Grenzo's ability doesn't actually track the zone of the card, but rather the card's attributes instead. Since his ability doesn't care about the zone as long as information is still within a public state, which is why the Wheel stops him, he can bring out the creature. The zone is entirely tertiary for his ability to function correctly, and often will matter only after post-resolution of the ability.

It seems like any old fart can be a legendary goblin these days.
Vampire Hexmage is in the set just to mess with him, right?

Honestly, if I were to build with him, I'd skip the whole counters thing and just run low power dudes. But he's a lot of fun either way.

Reito Lantern is actually IN the set, so you can live the dream in draft.

Topdecking, you say? Try bottomdecking for a change!

I like the dungeon theme Wizards decided to go for when dealing with cards on the bottom of the library.
The card they first came up with this is Cellar Door.
(Reito Lantern was the first card dealing with the bottom of the library, I think.)

Excellent card in every aspect! Interesting mechanics, decent power level, nice name, great art, intriguing flavor.

I really like this card and plan on building an EDH around him but I am a bit confused about how to build it, there are so many options. Firstly, something I haven't seen mentioned is the strange power of scry with him.

A low CMC aggro? Running few lands makes his ability more likely to strike gold, and powerful creatures do exist with power 2 or less. (E.g. Dark Confidant, Siege-Gang Commander and every other goblin, Magus of the Moon, Kargan Dragonlord, Kiki-jiki, Mirror Breaker, Stigma Lasher, Taurean Mauler, and many more) Plus, you can keep re-summoning without bothering with the X. This deck would be consistent but barring the goblin tribal option I fear would not pack the punch needed to kill in EDH. It would also be very costly.

Another option would be Voltron. Casting him early and stacking up power with equipments, you could threaten commander damage while also rummaging around for threats. The key would be a way to retrieve the equipments you mill. Goblin Welder, Moriok Scavenger could all help, but I can't think of much else. Best option is to just take what goes that way as a loss. I will probably be going for this option.

A strong guy that will ALWAYS be on curve for the p/t:CMC ratio, 2 relevent tribes (granted goblins more-so than rogue), and the ability to potentially explode the field with dudes? He is good. In the draft, he may just be a variable big dude, but you might be able to get some value out of his ability. There are some ways of stacking the bottom of your deck available in the set, as others have pointed out.

I would like see how well he would do as a general for EDH with ways to fully abuse his power.

Ultimately, even if he is just basically a fireball on legs, I am ok with this.

After stacking the bottom of your library... Mana Echoes

fun stuff here. don't forget that the ability is available at instant speed, which essentially means the creatures put into play have flash. Props to whoever manages to flash a phyrexian obliterater in front of an attacker.

Not to mention this kills the tunnel vision mill combos
