Frontier Siege, identified by card number 150 in the Commander 2017 set, is a green Enchantment in the Magic: The Gathering trading card game. Printed in 2017 with set code C17, this card requires a mana cost of {3}{G} and has a mana value of 4. Artists like James Ryman have contributed to the visual identity of this era, though the card’s primary appeal lies in its unique gameplay mechanics. The card presents a distinct strategic decision for players. As Frontier Siege enters the battlefield, the controller must choose between two effects: Khans or Dragons. Selecting the Khans option provides a consistent resource advantage, adding {G}{G} at the beginning of each of your main phases. This steady mana generation supports long-term strategy and deck development. Choosing the Dragons option offers a more aggressive approach, allowing you to have a creature with flying fight a target creature you don’t control whenever another flying creature enters the battlefield under your control. This dual-path design makes Frontier Siege a versatile piece for collectors and players interested in the Commander 2017 release. The card’s rarity as a Rare indicates its placement within the set’s distribution, making it a notable inclusion for those building complete sets or seeking specific gameplay interactions. Its green color identity aligns it with decks focused on growth, combat, and creature synergy. Whether used for its mana ramp in the Khans variant or its combat trick in the Dragons variant, Frontier Siege offers a flexible tool for strategic play. The card’s straightforward rules text and impactful effect have made it a memorable part of the Commander 2017 collection, appealing to those who appreciate meaningful choices in card effects.
