Gimli of the Glittering Caves Craft a team of legendary creatures for Gimli of the Glittering Caves to get their +1/+1 counter triggers
(4/14/2023) A Siege's controller can't be its protector
This set will be part of the August international release, which means that we could see that Charizard card here in the US before the one shown above
You could also consider including Purphoros, God of the Forge in your deck to make it so that whenever another creature enters the battlefield under your control you can deal two damage to each opponent
So while the card pool they have to fall back on is not going to perform anywhere near as well, they're only one or two overcooked cards away from bouncing right back into the pack
You can grab utility lands like Valakut, the Molten Pinnacle or Field of the Dead, assemble Dark Depths combo in a single attack, or get two Forests and win with the sheer mana advantage that comes with putting three lands into play a turn
