Before I get into the game summary, I want to note that I made a number of changes to the deck prior to this game. I will go over them at them end (I only saw one of the new cards anyway, but wanted to mention that the decklist did change).
Game Summary
This gave me 8 colorless mana and I used it to blink Relic-Warder a couple times to permanently exile Mogis, God of the Slaughter, and Gilded Lotus and then temporarily exiling another Gilded Lotus from Thrax.
I was able to land a Faerie Artisans which did a lot to keep me in the game. Both by triggering Ephara and getting me copies of things like Thrax and Sheoldred. While this was all happening, I was trying to take pot-shots at players with Ephara to keep their life totals down but I would say Artisans was the most important card I had for this game. Spellseeker was also key as it got me Mana Drain and Path to Exile. Archaeomancer got me back Mana Drain but I did have to give him up to Thrax attacking into me as they were getting an extra token of him thanks to Helm of the Host.
At one point, Vaevictus cast a Nyxbloom Ancient followed by some other creature (it is basically irrelevant as this is where they game ended). I got my copy from Artisans and they expected their next creature to get rid of the copy. "Not so!", said Displacer
In response to them casting their next creature, I blinked Artisans with Displacer. This allowed me to get another token but, most importantly, did not get rid of the Nyxbloom Ancient token. Right before it got back to my turn, I was able to blink Ancient and Artisans enough to get me 7 Ancients (I obviously could have gotten way more, but it was overkill and I liked to have a solid number to work with). This meant that each one of my lands tapped for 2,187 mana. I had 4 lands that produced colorless mana and those were the ones I cared about. So, I had 8,748 mana to work with. The game went around another turn and Thrax was gone. Vaevictus cast Hamletback Goliath.
As a side note, I also had Capsize in hand to effectively deal with everything on board anyway, but this was more enjoyable
And, the fun begins. We ended up just ending the game since they knew they couldn't deal with what I had on board, but I wanted to make a note here as to what the board state actually was at the end. And, again, I realize this is arguably larger if I spent the first three lands to get me more Ancients.
Damage Calculation
Once all the Goliaths enter, there is a total of 6,381,666 power total among all 1,458 Goliaths. The last Goliath has a power of 6 and the first Goliath has a power of 8,748. Assuming I didn't make a mistake somewhere. The only real reason I wanted to document this is because I have never gotten to an absurd amount of damage like this and I thought is was kind of a fun end to the game.
For arguments sake, if I had spent my first three lands to get more Ancients, this is what it would have looked like:
I tap my next land for 1,449,584,290,062,697,354,142,013,054,037,067,210,164,113,855,766,126,199,365,128,875,848,548,749,623,760,698,807,345,494,782,208,779,199,755,175,770,324,297,006,534,950,465,190,954,969,456,587,934,232,533,792,060,405,980,733,427,024,386,714,054,876,968,454,385,437,210,859,551,380,664,931,393,853,384,014,600,433,021,495,806,207,667,744,757,286,955,437,969,418,607,746,727,104,963,400,615,138,389,151,082,748,505,775,204,945,222,623,579,291,184,175,188,331,558,133,121 mana.
This gives me 241,597,381,677,116,225,690,335,509,006,177,868,360,685,642,627,687,699,894,188,145,974,758,124,937,293,449,801,224,249,130,368,129,866,625,862,628,387,382,834,422,491,744,198,492,494,909,431,322,372,088,965,343,400,996,788,904,504,064,452,342,479,494,742,397,572,868,476,591,896,777,488,565,642,230,669,100,072,170,249,301,034,611,290,792,881,159,239,661,569,767,957,787,850,827,233,435,856,398,191,847,124,750,962,534,157,537,103,929,881,864,029,198,055,259,689,589 Ancients including the 736 I had.
At this point, the online calculator I was using just said "nope" so I can't even get any further to figure out how much mana the next land tapped for. And this is still in the process of figuring out how much mana I had before I even get to the number of Goliaths. So, I guess I stop here
Final Musings and Changes
Here is the full list of changes I made. As I mentioned above, I saw a total of 1 of the new cards (the Leonin) so it wasn't the best showing for the new cards. But, in this game anyway, I never felt like I missed the cards I removed except maybe Return to Dust to deal with Mogis.
CUTS
I am hoping that my next game with the deck, next week most likely, will let me experience the other cards a little more so I can get a better feel for them. I don't want to edit the primer with these changes just yet in case there are other changes I want to make as these are more of a trial than things I expect to be permanent (at least, not permanent yet).
