Common Gameplay Mistakes

[Bayfighter]

-Killing my opponent's ally before attacking with Champion of Irum
-Using Shadow Energy before attacking with Aldmor Interceptor (who now has 1 less ATK point)
-Using fire attacks/abilities against Furrion Terror or electric attacks/abilities against Entangled Wisp
-Getting excited that I drew the exact game-changing card I needed, then sac'ing it into the Resource pile instead of casting it b/c I forgot to hit 'Skip' during the sacrifice phase

What other gameplay mistakes do you make that we all could learn from?

[BP Holy Punisher]

- Cast Thunderstrike Construct, target opposing ally but change your mind and hit cancel. This doesn't cancel the summoning, so you just missed the opportunity to reduce opp ally's hp and buff your ally
- Activate a seek ability (or summon Guardian of Unaxio) and cancel it. You just lost SE (or the card)
- Play a haste ally when opponent has Braxnorian Soldier or Groundshift.

[SamuelJ]

-using retreat/road less travelled/etc on an ally with steadfast

[tman507]

-Forgetting that comes into play abilities count as passives.
-Forgetting to attack with my Falseblood Cultist (or other non-Undead ally) before playing a Forgotten Horror.

[Lightning Fury]

- Forgetting allies with three health or less can't attack Braxnorian Soldier.
- Forgetting to kill Night Owl before casting an ally that then gives him stealth.
- Forgetting to draw first before anything else.
- Hitting cancel on DMT summon.
- Eladwen's ability has no effect on Stalactitan. Zaladar's ability has no effect on Entangled Wisp. Disciple of Aldmor immune to hero SE abilities.
- Casting another ally after casting Sabreen first, and not attacking with her
- Using Stop Thief on a support ability like Blood Moon.
- Forgetting Sustain requirements on items like Thriss Assault, Obelisk of Echoes
- Forgetting to say gg wp at the end of the match

My biggest mistake is forgetting the cost of cards before there played, I always seemed to miscaculate what cards cost and totally waste my turn

sacrificing your winning card instead of skipping
