New Demacia Landmark - The Grand Plaza

This card is... like ... who thought that 3 mana is appropriate for this effect in demacia? It basically is a free single combat + stat boost for every unit summoned which is way too good for 3 mana imo... like just think about the options it opens to SI Demacia decks where you can force death triggers way easier now and completely own the board... well we will see how it hits but im quite shure this hits hard

I saw this card and I said, out loud to myself, "What? Excuse me, what?" This card is absurdly strong. 

Elites and dragons are both gonna love this one. I can also see this work with a Lucian/Undying deck.

I really hope that this card isn't so powerful that it demands a nerf, because it opens up so many deckbuilding possibilities for Demacia that I think it deserves to be a staple like Single Combat. The most appropriate nerf I can see would be changing the Landmark to "When you summon an ally, give it Challenger this round. If it already has challenger, give it +1|+1 this round instead." In any case, I love the potential that this has with Shyvana and the Dragons in general. Late game, a lot of the dragons become really weak because they won't be able to gain Fury (such as the 4/4 Dragon). With Challenger, they are able to scale at least once and pull away units that could threaten your better dragons. This card also makes Stalking Broodmother into a superpowered Genevieve the turn it is played, which could cause that card to actually see play. Another great synergy I see is combining it with Legion Drummer to get units with Quick Attack and Challenger.
