The creature is the source of the damage, not Chandra's Ignition
If each creature the defending player controls can't block for any reason (such as being tapped), then Canopy Stalker isn't blocked
Rather, a second "reflexive" ability triggers when you exile a creature card from your graveyard this way
Since Im in green for this one, I can add a bit of extra ramp to help cast more expensive spells too
Erikas Invitation (Full Art) Market Price: $35.88 The standard waifu card of the set, Erikas Inivitation has an interesting ability that pulls a Basic Pokemon from an opponents hand and forcibly puts it in the Active Spot, presumably so that a player can pick it off with their much more powerful Pokemon
Also features a potent ability to draw cards late in the game: for five generic and one blue and a tap, sacrifice Blighted Cataract to draw two cards
