If only this CotD post was Call Energy, but oh well. Why I'm saying this. Well, that attack of Stantler is like Call Energy.
70 HP is OK for a basic. Fighting weakness isn't the best, and the retreat cost is average.
As I mentioned earlier, Stantler's first attack is just like Call Energy. It can grab two basic Pokemon out of your deck for one energy and then you can the Pokemon onto your bench. The second attack does 30 for three and causes confusion. Ehhh.........I don't think three energy for the second attack was that necessary.
Overall 2/10 in modified, 5/10 in limited, and 2/10 in unlimited
In modified, this card is definitely inferior to Call Energy. Stantler isn't that easy to use compared to Call Energy because with Call Energy, you can grab two Pokemon from your deck in a way where this can be done on any Pokemon. For Stantler, only Stantler can do it, not like Call Energy where it can work with anything, so Stantler is definitely not the best card here.
In limited, Stantler sees some better uses. There is no Call Energy here, so this card can be a great starter whenever you are in the need of basics. If you pull out a Stantler, I would recommend using him as a starter that's for sure.
In unlimited, this card can see only a little use. Well, once again, he could be a good starter, but Call Energy outclasses it here once again.
