Yu-Gi-Oh: 10 Most Powerful Unbanned Cards In The Game

10. Aleister The Invoker

Aleister The Invoker and the Invoked engine has been a meta mainstay since its release all the way back in 2017s Fusion Enforcers.

Aleister is a spellcaster obsessed with fusing his body with the elements via sacred magic. In the deck Aleister the glue that holds the core together and allows for the core to be combined with a wide variety of other archetypes.

Aleister is your main normal summon, a level four monster that allows you to search out Invocation, the decks busted fusion spell. One of the reasons he's so good is card economy as he instantly replaces himself with a key spell card on summon.

Using Aleister and Invocation you have a swiss army knife of powerful fusion monsters at your disposal. The line of play is often the same, Aleister will get Invocation, you'll fuse Aleister away alongside one of your or your opponents monsters (Invocation allows you to use your opponent's monsters as material if in the graveyard) and you'll return Invocation back to the deck to return Aleister back to your hand ready for his second ability.

His second ability is just icing on the cake allowing you to discard Aleister from your hand to increase the attack of one of your fusion monsters by 1000. When combined with Invoked Purgotrio is can the difference between winning and losing and the fact that you can add Aleister back to your hand from your graveyard via the ability of Invocation makes for ''naturally easy plays''.

The engine melds well with other archetypes and since its release its seen tournament success with Mekk-Knights, Blue-Eyes and most recently with Shaddolls.

It's worthy of a ban because its had its day in the sun and people are sick to death of the common play patterns over and over. When added to other archetypes it dilutes the duelist's creativity as it quickly locks up extra deck space (you only have 15 slots and over half will be taken up with Invoked fusion monsters) and main deck space, you need the main man himself, the field spell, Invocation etc.

Aleister was limited to one in the OCG and parts of the deck has been limited in the TCG so Konami definitely has their eye on the core.
