Not impractical at all. Is that momentum needed?

If opponent has a wings, you only did 54 damage.

Not impractical enough. You need Mitosis + SoR on the Druidic staff before Quintessence.

[ddevans96]

Mitosis doesn't work on weapons.

Aw, snap. It's as impractical as it is gonna get!

Momentummed adrenastaves is a known, used deck, and Kakerlake made a VERY good one with TU too.
You saw the title has an "impractical" in there, right?

 True, but it is impractical since it is difficult to perform a combo which needs 5 cards from 4 different elements (3 if you consider Animate Weapon an 'other' card). Sometimes or in some decks you can be able to perform it, but how many of these decks really exists and how can it be reliable to draw all these cards without using cards? 
 For the same reason, I personally call 'impractical' the Instosis Combo, despite the fact it is one of the most successful decks around.

If you can use it, especially with success like instosis, it's practical.

5 damage per turn to the oponent, plus the poison damage 

Replace LS with afla, and double the damage.

 I know what impractical means, however I don't think in this topic is used with its literally sense. It is used as a way to describe an amazing card combo which is possible to be accomplished only in a deck which has been designed for this purpose. There are several examples in here.
