Forbidden Chalice

Forbidden Chalice was a popular pick previously, during the OCG 2017.04 Metagame (1 Apr 2017 – 30 Jun 2017).

Today we will be looking at the reasons for Forbidden Chalice‘s popularity and speculate about its future utility.

Forbidden Chalice
Quick-Play Spell
Target 1 face-up monster on the field; until the end of this turn, that target gains 400 ATK, but its effects are negated.



Zoodiac monsters possess a variable ATK and DEF stat, calculated by its Zoodiac Xyz Materials. This counts towards an effect. Placing Forbidden Chalice on Zoodiac monster negates it effect and reduces its ATK to just 400, making it easier to bypass. It also nullifies Zoodiac Whiptail as a threat.

In Zoodiac mirror matches, it perfectly answers an opposing Zoodiac Hammerkong which may be preventing a player from using the effect of Zoodiac Whiptail or Zoodiac Tigermortar.


True Draco

True Draco contributed largely to the wide usage of Forbidden Chalice.

As a True Draco player, the Quick-Play Spell Forbidden Chalice shares an unobvious synergy with Dragonic Diagram. When Dragonic Diagram is used at Chain Link 1, Forbidden Chalice can be responded as Chain Link 2. The resolution of the Chain Links hence allow Dragonic Diagram to destroy Forbidden Chalice.

In Mirror Matches, Forbidden Chalice doubles as an answer to True Draco monsters such as Dinomight Knight, the True Dracofighter, when its effect is activated in response to Dragonic Diagram‘s effect. Forbidden Chalice can thus negate the opposing True Draco monster’s effect while being destroyed to resolve Dragonic Diagram.


True King of All Calamities

True King of All Calamities has a fearsome lockdown effect which is commonly activated during the opponent’s Standby Phase. Disabling the effects of cards such as Spellbook Magician of Prophecy and the Windwitch monsters, it will prevent plays from taking off, distancing the gap in advantage.

Forbidden Chalice can change that by negating True King of All Calamities in response to its effect activation, being a potential lifesaver.


Breakthrough Skill

What sets Forbidden Chalice apart from Breakthrough Skill is not the ATK gain, but Forbidden Chalice‘s Quick-Play Spell status. Traps generally perform poorly when a player is going second. Forbidden Chalice allows for negation even when a player is starting second. This allows one to tear apart lockdowns and enable plays by negating the effects of Master Peace, the True Dracoslaying King and Crystal Wing Synchro Dragon.

Forbidden Chalice is usually withheld in the hand, waiting for the right moment for it to be used, rather than dedicating it as a set card in the Spell/Trap zone. It excels at negating monster effects at Chain Link 2 and above, after baiting out an opposing Monster’s effect.


July 2017

In the current metagame (1 July 2017 – 30 Sep 2017), Forbidden Chalice is not a popular choice as before. However, it remains useful.

  • Invoked remains to be a threat in this format. Forbidden Chalice can serve as an out to Invoked Mechaba.
  • Against True King Yang Zing Dinosaur, it can stop the Synchro Summon of Herald of Arc Light during your turn and prevent Ultimate Conductor Tyranno from interrupting your plays.



Forbidden Chalice is useful as a staple as it can cater to a ton of threats.

Moving forward, with plenty of support and attention paid to Link Monsters, Forbidden Chalice is likely to remain useful. Link Monsters such as Proxy Dragon, Topologic Bomber Dragon and Firewall Dragon will likely see an increase in usage. Forbidden Chalice answers these threats effectively without over-dedicating your deck to clear these threats.

With Deck Build Pack: Spirit Warriors around the corner, Forbidden Chalice is likely to continue seeing play. It can prevent Magibullet monsters from gaining pluses and answer Legendary Six Samurai – Shi En‘s negation.
