Runeblood Barrier and Ironsong Pride
The vast majority of aura cards are templated so that however they enter the arena (from being played or from an effect that just puts them there), their effects will trigger and resolve just the same. A small oversight during the proofing process led to Ironsong Pride and Runeblood Barrier being exceptions to this, where their text was templated to be in line with resolution abilities (i.e. happens when it resolves on the stack), as opposed to being triggered abilities (i.e. happens as a result of it entering the arena from anywhere). To bring these cards in line with other auras in the game and have consistency in how our players perceive the functionality of these cards, we have decided to issue an errata to update these cards to have triggered abilities that trigger when they enter the arena.
Ironsong Pride
Warrior Instant - Aura
(RED) 1{r}
When this enters the arena, put a +1{p} counter on target sword you control.
When this leaves the arena, remove all +1{p} counters from swords you control.
At the beginning of your end phase, if a sword has not hit this turn, destroy this.
Runeblood Barrier
Runeblade Action - Aura
(YEL) 3{r} 2{d}
When this enters the arena, create 4 Runechant tokens.
If your hero would be dealt damage, instead destroy that many Runechant tokens you control and prevent 1 damage for each Runechant token destroyed this way.
At the beginning of your action phase, destroy this.
