The Bleed cards created by Garrote still have the bug where they benefit from your Spell Damage, but other damage spells have never done this! Bombs from your deck have exactly the same effect, being draw from your deck and dealing damage to a player’s face, but they do not experience the effect of Spell Damage.
In particular, even the temporary spell damage from Talented Arcanist, which is only supposed to apply to the next spell you play somehow affects the damage from Bleed cards drawn after you play it?!?! Why does this card have such completely uninuitive, unintended effects that completely ruin gameplay and are 100% inconsistent with similar past cards?
The Talented Arcanist affecting Bleeds is a very clear bug which some players are DELIBERATELY exploiting, but by all rights the entire fact that the Bleed cards benefit from Spell Damage is also not consistent with other similar effects.
